Ensembl UK shutdown - 8/9th January 2011

Owing to problems with our data centre cooling system, the Sanger network will be offline from around 4.30pm on Friday 7th January until the evening of Sunday 9th January (UK time).

This means that all UK-based Ensembl sites, including www.ensembl.org, archives and pre site, will be unavailable from late Friday afternoon until Monday morning.

However, you can still browse the genome using our US (Ensembl west & east) and Asia mirror sites. Services that depend on machines based in the UK, i.e. BLAST/BLAT and user logins, will be disabled during this time.

In the case of bacteria, fungi, metazoa, plants, and protists at www.ensemblgenomes.org, no mirror site is as of yet available. Those services will not be running over the weekend.

Please accept our apologies for any inconvenience caused. A reminder will be sent out to the announce@ensembl.org mailing list, and on our Twitter feed, nearer the time.

Seasons Greetings and Upcoming Features

Happy holidays from Ensembl! Here in Hinxton, we are planning new developments for the new year (what else would we do with all this snow!) Some of the highlights planned for early next year include:

  • The first gene set for turkey in Ensembl, and inclusion of turkey into pairwise (between two species) whole-genome alignments and multiple species alignments (including a new 3-way avian alignment).
  • Inclusion (merge) of manual curation of the zebra-fish genome by the HAVANA group into the Ensembl gene set.
  • Update to dbSNP 132 for variations in the human genome.
  • Sea Urchin (Strongylocentrotus purpuratus) and Honey Bee (Apis mellifera) genomes in the Ensembl Metazoa site. See other upcoming species to Ensembl genomes here.
Don't forget, an overview of upcoming annotation to Ensembl is on our roadmap.

For those of you going on holiday soon, enjoy! We look forward to supporting all your cutting-edge scientific endeavors in 2011.

Beds, Wigs, BAMs and Variants for Flies, Rust, Aphids and 301 other species


Now that Ensembl Genomes has moved onto the 60 code base, all the goodies in Ensembl's user data site are available across all 304 species in Ensembl genomes - from tiny bacteria to crazy big plants.

One of these is uploads of BAMs, Wigs, Beds in the location based view. For example, if you have the following file to specify a SNP in Drosophila

2L 356013 356013 C/T

By using the Variant Effect Predictor, accessible from Tools on the top of each page, or the 'Manage your data' link at the left of pages, one can get the effect (synonymous, non synonymous, in a UTR etc) for the variant.

(You click on "Variant Effect Predictor", upload a text file of chr, position, allele and hit go) This can also be run as script using the API (the database is internet accessible so you just need to have an internet connection, Perl, MySQL client libraries and the Ensembl code base installed).

In addition, the full set of visualisation tools for your own data is also now accessible for all Ensembl Genomes species. For example, this bedGraph file:

track type=bedGraph name="BedGraph Format" description="BedGraph format" priority=20
2L 21302000 21302300 -1.0
2L 21302300 21302600 -0.75
2L 21302600 21302900 -0.50
2L 21302900 21303200 -0.25
2L 21303200 21303500 0.0
2L 21303500 21303800 0.25
2L 21303800 21304100 0.50
2L 21304100 21304400 0.75

Will render a nice little variable height picture in the main contigview display. Other options are available (like Bed and Wig format) - many of which people will know from UCSC. Come, try it out, and give us feedback at helpdesk@ensembl.org

01 December, 2010

Beds, Wigs and BAMs

The Ensembl 60 release sees two changes in our data upload capabilities

First off Ensembl can now "attach" a BAM file. BAM is the compressed form SAM - Sequence AlignMent files - which has become the dominant way to package up next-generation sequencing data. A BAM (or SAM file) has both the sequence and the alignment of a set of reads in a compact form (BAM makes it even more compact). Critically you can index a BAM file allowing programs rapid access to particular "Slices" of the reads by genomic position. Alignment tools such as Maq, BWA, SOAP can produce BAM files; a variety of analysis tools are written around BAM files, and now Ensembl can view BAM files.


To make a BAM file viewable you need to have access to a website where you can put files (like you local web space, perhaps an institutional thing). Call MyGreatExperiment.bam. You then need to index the BAM file using one of the tools - samtools is the usual one to do this, making a MyGreatExperiment.bam.bai (BAM index) precisely along side it (The Ensembl code is going to make the assumption that the index is called filename.bai). Then go to "Manage your Data" button on any web page in Ensembl, and go to the "Attach BAM" section. And then browse your RNA-seq, Chip-seq, Exome data to your hearts content!


In addition, we've spruced up our functionality and documentation on the UCSC file formats of Bed, BedGraph and Wig. Take a look at the "File Upload" and "Attach URL" forms, and the documentation. Now we precisely indicate what attributes you can use in each of these formats. Our goal is to make Ensembl as useful as possible to as broad a set of users as possible, so let us know if you find something confusing and/or you have a Bed/Bedgraph/Wig file that works for UCSC but doesn't work on Ensembl.


This is of course available across all 50 species in Ensembl, and in a couple of weeks, when Ensembl Genomes 7 is out, across another 50 eukaryotes from protists to plants and about 250 different bacteria.

Comments are welcome - either on this blog or email to helpdesk@ensembl.org

10 November, 2010

US East coast Ensembl mirror now available

We are pleased to announce the public availability of a second Ensembl mirror in the USA. This can be found at http://useast.ensembl.org/ . This provides a fully functional Ensembl website, but there are some things to note which I've listed below.

Redirection

We don't automatically redirect users to the new mirror, although we have plans for this in future. So for now you'll need to explicitly visit http://useast.ensembl.org/ to access it.

User logins

If you use the login functionality, your existing login will work on http://useast.ensembl.org/ , although configuration changes will not be reflected between sites. We plan to support shared logins very soon.

Other services

We don't yet offer the Biomart or BLAST/BLAT services on the new mirror; these will come in the near future. We currently have no plans to offer a US-based MySQL mirror, so you should continue use ensembldb.ensembl.org for MySQL queries.

We're very keen to hear your experiences with this new mirror, particularly from our US users, please use the Helpdesk in the first instance, or contact me directly. We also have advanced plans for mirrors in other parts of the world, so stay tuned!

Release 60

The Ensembl project is pleased to announce release 60 of Ensembl. Highlights of this release are:

* New species - Giant Panda
* New assemblies and genebuilds for zebrafish and rabbit
* Improved design of the Variation Table
* New display for GO terms
* Improved navigation on Region in Detail, including autocompletion of gene display names (e.g. HGNC)

More database maintenance

Unfortunately our database storage is still unstable, and all Ensembl dbs are being taken offline this afternoon for emergency maintenance work. Please accept our apologies for any inconvenience caused.

This will affect all UK-based sites, including www.ensembl.org, pre.ensembl.org, Vega and the archives. The US West mirror, uswest.ensembl.org, will be running with reduced functionality (no user logins or BLAST, which depend on Sanger dbs), and the cloud-based useast.ensembl.org should be unaffected.

For detailed web status updates, you can also follow us at twitter.com/ensembl_web.

Ensembl Wants to Know What You Think!

Dear Ensembl Users,

Our survey is still open. Please consider giving us 10 minutes of your time to let us know what you think of our website. This will help us make Ensembl more usable.

Click on the link, and pass it around! We want to hear from new users as well.

http://www.surveymonkey.com/s/KCR6WN2

Many thanks,
The Ensembl Team

04 October, 2010

Reduced website functionality on 5th October 2010. - Now postponed


This work has been postponed and the Ensembl site is now running as normal. We will update the blog informing you when this work is rescheduled.


The Systems team at the Sanger Institute need to carry out emergency maintenance to some of the database servers running the ensembl websites from 9.30 am tomorrow morning. This means that we will be running the live Ensembl site with reduced functionality and the Pre, Vega, NCBI36 and archive sites will temporarily be off line.

Blast, Biomart, user-logins and search will all be unavailable. The entire Ensembl website should be considered as "At risk", however should the main site go down the two mirror sites, uswest.ensembl.org and useast.ensembl.org should still be available although these too will have reduced functionality.

We apologise for inconvenience this may cause and will work to ensure the disruption occurs for the shortest time possible.

02 October, 2010

Main Ensembl site offline - now fixed (3/10/10 6pm)

The site is now back.

There is a problem with the storage attached to the database servers which has taken the main Ensembl site offline. Please use one of our two mirror sites http://uswest.ensembl.org and http://useast.ensembl.org. We will update the blog when the main site is working again, we apologise for any inconvenience caused.

28 September, 2010

Changes to mysqlimport

Owing to problems with BLOB data in some tables, we have had to change the way these tables are dumped, which in turn means a change to the mysqlimport parameters.

It has been necessary to escape the table fields when dumping the MySQL text files. Hence to import successfully, a field escape parameter needs to be specified when using mysqlimport, e.g.

mysqlimport -h your_host -u write_user -p write_pass -P 3306 --fields_escaped_by=\\ database_name /full/path/to/table_name.txt

Tables affected in Release 59 are:

* homo_sapiens_funcgen_59_37d.result_feature
* mus_musculus_funcgen_59_37l.result_feature
* ensembl_compara_59.conservation_scores

and the meta_conf__xml__dm and meta_template__xml__dm tables in all mart databases.

From release 60, all Ensembl mysql dumps will be done this way, so you will need to use the above parameters on all imports.

24 September, 2010

Ensembl Events in October 2010

In October we have the following Ensembl events:

12 Oct: Ensembl module in the EBI Bioinformatics Roadshow, Dokuz Eylul University, Izmir, Turkey

Changing to LASTZ


People following the declarations of intentions for the next release (these are sent to announce@ensembl.org) may have noticed that we are releasing LASTZ pairwise alignments instead of BLASTZ ones. LASTZ is written by Bob Harris from the Penn State University as a replacement of BLASTZ, as BLASTZ is now considered obsolete (read the announcement).

This is the first release where we use LASTZ for the new alignments. We will update the previous alignments in the following releases.

09 September, 2010

A.mel vs A.mel

Ensembl is already working on the forthcoming release (e60!). The declaration of intentions have been published and include the new Giant Panda (Ailuropoda melanoleuca) genome.

While I was looking at the alignments we are planing to release, I saw the H.sap-A.mel LASTZ-net alignments. Hey! I thought we banned Apis mellifera from Ensembl long time ago.

Then I realised that the scientific names of both the honey bee and the giant panda start with the same letters. So, don't get confused, one of them eats flowers and makes honey, while the other one eats bamboo and makes very nice teddies!

01 September, 2010

Tell Us What You Think!

To new and frequent Ensembl users,

We are continuously striving to improve our web interface at www.ensembl.org.

Please let us know how we're doing!

The survey should take 10-15 minutes.

Ensembl browser workshops Western US January 2011

The Ensembl Outreach team is currently looking into the possibility of giving some 1-day Ensembl browser workshops in the Western US in the period directly before or after the Plant and Animal Genome Conference in San Diego, which takes place from 15-19 January 2011. Hosting institutions would only have to pay the instructor's expenses (accommodation and subsistence) and would share the domestic travel costs, but we would not otherwise charge for the workshops.

For more information about our browser workshops, please have a look here.

Interested? Please contact me for more details at bert@ebi.ac.uk.

19 August, 2010

Networks problems at the Sanger site

The Systems team at the Sanger Institute have resolved the network problems and http://www.ensembl.org is now back up and running as normal.

The Sanger Institute is currently experiencing networks problems which have taken the main Ensembl site offline. Please use one of our two mirror sites http://uswest.ensembl.org and http://useast.ensembl.org We will update the blog when the main site is working again, we apologise for any inconvenience caused.

18 August, 2010

Maintenance Finished

Hi Ensembl Users,

The work is finished, and search is working on archives again.


Just a warning. Maintenance work this afternoon (18 Aug, 2:45 to 5 PM in the UK) could affect the live site. If this is the case, please try our mirror site at uswest.ensembl.org

Search will be temporarily disabled on the archive sites for versions 55-57. If BioMart queries are slow, please use the interface at www.biomart.org.

Regards,
The Ensembl Team

16 August, 2010

Ensembl in Toronto

Ensembl will be training at the Terrence Donnelly Centre for Cellular and Bio-molecular Research, University of Toronto this coming month of September, where we will be running two workshops (7 & 8 September).

In these workshops we will provide an overview of recent and future developments in the Project, as well as focus on some particular topics such as variation or gene annotation. As always, we encourage participants to come with their own research questions. Note that participants have to come with their own laptop, other than that you only need some general knowledge of molecular biology/genomics and familiarity with web browsers. If you have any additional questions you can get information from the organisers. In addition to the University of Toronto, this course is sponsored by the OICR, CIHR-IRSC, and EMBL-EBI.

Regulatory Build now Cell Type specific

Since release 58, the Ensembl Regulatory Build has been cell type specific. Regulatory Features are defined as sites of open chromatin which are potentially involved in gene regulation. These are built using data from different cell types, resulting in differing structures, attributes and classifications across the various cell types.

Release 59 also boasts greater coverage due to the incorporation of more data sets (see previous blog post), and a new 'projection' methodology. Projection allows Regulatory Features to be built on cell lines with sparse data, and also consolidates existing higher quality builds. The result of these changes is an increase in the number of Regulatory Features per cell type, as well as an improvement in the number of features which are assigned a classification e.g. Gene Associated or Promoter Associated etc.

The 'Regulation' panel has also been updated to reflect the new cell type specific nature of the build e.g. ENSR00000515919. The 'Details by cell line' view is now split into several sections, each showing data for a specific cell line. The uppermost section details a species 'MultiCell' cell line, showing data used to define the core regions of the given Regulatory Feature. More information on this view can be found here. We are always looking at ways to improve our Regulatory Build process, some areas we are currently considering are listed in our development road map.

13 August, 2010

New ChIP-Seq data and visualisation

Over the last 3 releases we have significantly increased the content of the functional genomics databases, by including data from large public projects such as ENCODE and The Epigenomics Roadmap. In release 59 we have over 200 human data sets representing 10 cell types, 41 histone modifications and 14 transcription factors. These numbers will steadily increase in the forthcoming releases as more data is incorporated.

These data sets are now available in 'Region In Detail'. Cell type tracks can be turned on via the 'Functional genomics' menu of the configuration panel - click on 'configure this page' on the left to access it. These are split into 'Core' and 'Other' evidence types, reflecting how we deal with these data within the Regulatory Build. Display options include a peak track, with the underlying raw data is available as a 'multi-wiggle' track. Further configuration is available via the 'Cell/Tissue' tab, where individual feature types can be turned on or off.

Work is ongoing to improve the flexibility of these displays.

05 August, 2010

Human GRCh37 assembly patches

Ensembl release 59 includes the first human assembly patches released by the Genome Reference Consortium (GRC).

The goal of the GRC is to ensure that the human reference assembly is biologically relevant by closing gaps, fixing errors and representing complex variation. Their ongoing efforts are made available to the community via minor releases called patches. The patches do not change the chromosome coordinate system but do provide either a new alternate haplotype (novel patch) or provide a preview of the chromosome tiling path for that region in the next major release (fix patch).

The patched update GRCh37.p1 affects only 2 regions of the reference assembly.The patch update GRCh37.p1 includes:

Fix Patch: HG79_PATCH (GL339450.1) on chromosome 9, correction for the ABO gene. Click here for an example region.

Novel Patch: HSCHR5_1_CTG1 (GL339449.1) on chromosome 5. This patch provides an alternative region (haplotype). Click here for an example region.

The two patched regions have undergone preliminary gene annotation. Human cDNAs with their annotated ORFs were aligned to the genome using the Exonerate cdna2genome model to generate coding transcripts.

We expect future patch releases on a quarterly basis.

28 July, 2010

Ensembl Events in August 2010

Although it's Summer vacation time, there are still a few Ensembl events scheduled the coming month:

18 Aug: Ensembl module in the EURASNET Workshop on Structural Bioinformatics of RNA & RNP at the Adam Mickiewicz University, Poznan, Poland
29 Aug: Ensembl module at the ESF European Meeting on Next Generation Sequencing at Leiden University Medical Center, The Netherlands

For details about these and other upcoming events, please have a look at the complete list of Ensembl training events.

27 July, 2010

Changes to Ensembl Mailing Lists

In the near future, we will be changing the way that the ensembl-dev and ensembl-announce mailing lists are managed.

The move to new hardware and list management software will increase responsiveness on the lists (ensembl-dev in particular has suffered from slow deliveries for some time), and in time will also allow us to provide a searchable archive of past posts.

The list addresses will change with the move:

  • ensembl-dev@ebi.ac.uk becomes dev@ensembl.org
  • ensembl-announce@ebi.ac.uk becomes announce@ensembl.org
The new addresses are active now.

All subscribers to the old lists have been moved to the new lists. Posts to the old list addresses will be automatically forwarded for a short time, but please update your email address books and any spam filters to reflect the new address list.

Information about the new lists, including details on how to subscribe and unsubscribe, can be found at http://lists.ensembl.org/.

As before, dev@ensembl.org is an open list which any subscriber can post to. Posting to announce@ensembl.org is restricted to Ensembl people.

07 July, 2010

All sites up and running

All Ensembl sites are up and running - the outage referred to in the previous post only lasted for about 20 minutes.

02 July, 2010

Site problems - further details and temporary alternatives

As Anne mentioned, at approximately 03:00 UK time on 2 July, the Sanger Institute Data Centre suffered a power failure. The effects of this have taken taken the main Ensembl web site and other resources off line. We are working to get the services restored.


In the mean time, we have two US mirror sites available:

http://useast.ensembl.org is recently launched and provides genome browsing and search facility.

http://uswest.ensembl.org provides genome browsing, but search relies on the main site in the UK.

Please note that BLAST services require the main site at Hinxton and will not be available until the systems have been restored.

Thank you for your patience and we apologise for any inconvenience caused.

More power failures

We are currently experiencing further system problems caused by a generator failure at approximately 3am UK time. Our IT staff are working to restore service, and we apologise for any inconvenience caused.

Our US mirror, uswest.ensembl.org, is still available, although features that depend on Sanger services (user accounts, BLAST) will not be working.

24 June, 2010

Ensembl Genomes browser workshops

The Ensembl project has focused on vertebrate organisms for the past ten years. Since Jan 2009, a sister project has formed, Ensembl Genomes, extending analysis to invertebrates, protists, plants, fungi and bacteria.

We do now offer separate workshops on both Ensembl and Ensembl Genomes. Though the browsing is similar, specifics can vary. For example, the genes in most non-vertebrate genomes are determined using different rules than in vertebrate genomes.

So, if you are thinking of hosting a browser workshop and you know your audience will mainly consist of researchers working on non-vertebrate genomes, the Ensembl Genomes browser is the right choice for you!

For more detailed information on the Ensembl Genomes browser workshops please have a look here.

22 June, 2010

Power failure

We are currently experiencing a power failure which has taken the main Ensembl site offline. Our mirror site uswest.ensembl.org is still running so please use this until we have the main site back online.

21 June, 2010

Ensembl Developers Workshop at Genome Informatics 2010

Ensembl announces a workshop for developers that will take place at the Wellcome Trust Genome Campus, Hinxton, UK. The workshop runs in the week of the Genome Informatics conference, from Monday 13 September until midday Wednesday 15 September 2010, and will cover the same content as in previous years.

Ensembl developers will present sessions on how to create your own core database, including the loading of a genome assembly into a database and the running of simple analyses using the Ensembl genebuild pipeline.

As this workshop is aimed at developers, we will be exploring the underlying code-base of the Ensembl Software System. The workshop comprises presentations around Ensembl as well as practical sessions. We would like to point out that this is not a 'learning how to program in Perl' workshop.

For the successful completion of the workshop exercises, participants will be expected to have comprehensive experience in PERL programming and a background in object oriented programming techniques. Familiarity with Perl, a Unix/Linux environment, databases and structured query languages (MySQL) are needed to follow the workshop and the programming examples. Knowledge of the Ensembl core API is essential. The workshop is suitable for people who have access to small- to large scale compute resources, and who plan to run genome-wide analyses on large-scale data sets.

The workshop will be given by:

• Bronwen Aken (Ensembl Genome Annotation team)
• Jan-Hinnerk Vogel (Ensembl Genome Annotation team)

Additional presenters will attend depending on the number of participants registering.

At the end of this course, attendees will

• have a good understanding of Ensembl's annotation pipeline

SNPs in high LD


A new section has been added to the variation page in Ensembl 58 that allows you to find other variations in strong linkage disequilibrium with the SNP you are viewing.

Clicking on "Linked variations" from the menu on the left hand side of the variation page takes you to a view like this one for rs1333049. Linkage disequilibrium values are calcuated on the fly and presented in one table for each population.

The table shows both r2 and D' values, along with the distance between the linked and current variations, any overlapping genes and any phenotypes associated with the linked variations. The table can be sorted by any of these columns by clicking on the column header (see previous post). The view is extensively configurable - clicking on Configure this page allows you to select populations to be displayed, change the distance over which linked variations are looked for, and filter the variations returned.

This view is currently only available for Ensembl Human, and is limited to variations with enough associated genotypes to calculate linkage disequilibrium values.

New Features to Aid Browsing

With the recent release of version 58, we are pleased to announce a few features designed to make genome browsing simpler. Have you noticed the search function in the individual tables? For example, in the Gene tab: "Variation Table", search for a variation ID.

Have a look at our sortable tables. In this example, we can sort by ID, Type, location, allele, source, or validation status. Use the arrows next to the column title to choose a new column to sort by. Searchable, and sortable, tables can also be found for orthologues, variations across individuals or strains, protein motifs and domains, and more.

If you are browsing a genomic region, you may have noticed that the Location tab: "Region in detail" view has a sliding zoom bar. Zoom out to view neighbouring genes and features, or zoom in to your favourite exon.

Zebrafish RNA-seq gene models

We have been developing a pipeline to build gene models using only RNA-seq data. For release 58 we have added a preliminary set of Zebrafish RNA-seq gene models with an intention to integrate this new source of evidence into a full genebuild soon.

Zebrafish transcriptome data from 9 tissues were used to build a set of genes and splice variants. For each loci we chose the variant with the highest read support to display, further details on the process are available here.
To display the genes, go to the Region in Detail, or Region Overview. Use the "Configure this page" button and select "RNASeq Genes" from the "Genes" menu. The "Supporting DNA Alignments" menu contains supporting exon and intron features from each of the nine tissues. Clicking on these features in Ensembl location pages shows a simple read count for the intron features and RPKM values for transcripts and exons, (reads per kilobase of model per million mapped reads, from Mortazavi Nature Methods 2008).

This is a first attempt at visualising tissue specific read depth and alternative splicing, which we hope to develop further in the future.

GERP constrained elements via DAS

It is now possible to get the GERP constrained elements via the DAS protocol. For instance the DAS command to get all the GERP elements on the BRCA2 gene (Human chr 13: 32889611-32973347) is:
http://www.ensembl.org/das/Homo_sapiens.GRCh37.constrained_element/features?segment=13:32889611,32973347

By default, you obtain both the constrained derived from our 16-way amniote alignments and the 33-way placental mammals ones (these include all the low-coverage genomes). You can filter the elements you want by using the argument type:
http://www.ensembl.org/das/Homo_sapiens.GRCh37.constrained_element/features?segment=13:32889611,32973347;type=33_eutherian_mammals

Read more on DAS or on the multiple alignments and constrained elements.

Which whole-genome multiple aligner? Pecan!

Comparing and assessing the quality of whole-genome multiple alignments is a difficult task. In the protein world, many mathematical models are available. They are based on synonymous and non-synonymous substitutions and the physicochemical similarities among the aminoacids. None of this can be applied to non-coding sequences, the 99% of the human genome.

There are two main trends for whole-genome alignments. Authors have either used genomic features like ancestral repeats or have developed phylogenetic models to generate synthetic sequences for which the "real" alignment is known.

Two articles have been published recently, one proposing a new method based on artificial sequences (Kim & Sinha, BMC Bioinformatics 2010, 11:54) and the other one looking at the coverage, agreement and accuracy of the alignments in the ENCODE pilot regions (Chen & Tompa, Nature Biotechnology 2010, doi:10.1038/nbt.1637).

According to both studies, Pecan is the strongest contender, showing the clear advantage of using a consistency-based approach (see Paten et al., Genome Res. 2008, 18:1814-28) to align the sequences.

Musing about Fish Alignments.

Release 57 saw the release of a 5-way EPO alignment across the telost fish - Zebrafish, Stickleback, Medaka, Tetraodon and Fugu. Just recently I've spent some time browsing through them. They are very interesting, with the ancestral duplication in Fish showing more complex homology relationships than in mammals. Here's a nice, clean example

Simple Fish multiple alignments

Here is a far more complex region, when ENREDO has clearly picked up the ancestral duplication but is struggling to make it colinear across the entire region

Complex Fish multiple alignments

One thing which I don't think most people appreciate is the incredible phylogenetic depth in the telost linage. In terms of "millions of years of evolution" or "sequence divergence" actually the deepest splits in the telosts - such as ZebraFish to Stickleback - are almost as deep as telosts to mammals - certainly deeper than birds to mammals. So this is asking alot to find good, clearly co linear stretches, in particular when you think of the draft nature of these genomes.

Chatting to Javier, it might be much better to also look at a 4-way EPO on the "Stickleback" side of the telost linage, in other words, Medaka/Stickleback/Fugu/Tetraodon. This I think will come together better (in fact most of the "nice" regions in the 5-way EPO are actually regions without ZebraFish) and we might be able to look at taking that ancestral chromosome ordering and perhaps sequence in comparisons to Zebrafish.

Ensembl, Xfam and HMMs

This week, Albert Vilella and myself participated in the Xfam consortium meeting. The meeting focussed on protein, domains and ncRNA classification, and on the new developments of the HMMER package.

Although Ensembl is not part of Xfam, we share many interests. We are getting increasingly interested in the use HMMER models, especially since the release of HMMER3.0. Also, in the forthcoming release (version 58), Ensembl will provide gene trees for ncRNAs. Most of these ncRNA genes are annotated using Rfam models.

Stay tuned for more!

Neandertal Genome Browser

In collaboration with the Neandertal Genome Project, we have created an Ensembl-style browser of the Neandertal data available at http://projects.ensembl.org/neandertal. A draft sequence of the Neandertal genome was published in the May 7 issue of Science.

The Neandertal browser includes the ability to visualise the Neandertal data using the new Resembl code developed in collaboration with Illumina. The Resembl code will be introduced in the 1000 Genomes browser later this month and in Ensembl over the summer.

Data include:
- Neandertal sequencing reads from all 6 Neandertal fossils
- Neandertal contigs/consensus from all individuals combined
- Modern human sequencing reads to put the divergence of the Neandertal genomes into perspective
- Selective sweep scan to detect positive selection in early modern humans
- A catalog of changes consisting of Neandertal alleles for positions of non-synonymous difference between human and chimpanzee

Full details of the data types and instructions for using our new display tools are available on the data information page.

Links are also provided from the Neandertal Browser home page to the raw sequence data stored at the EBI for the Neandertal genome project and the modern human genome data.


Further information about the project is available from the project page at Max Planck Institute for Evolutionary Anthropology, from the genome paper and from other companion papers in the same issue of science.

We thank Janet Kelso, Ed Green and Udo Stenzel at the MPI for assistance and Eugene Kulesha at the EBI for work to create the Neandertal browser.

SNPedia in Ensembl


Ensembl is always extending the variation pages to include more information. Did you know that the latest data from SNPedia is now available?

SNPedia is a wiki-style resource for human genetics with public annotation of over 11,000 SNPs, released under a Creative Commons style license. We have integrated it into Ensembl, so you can view these SNP reports along with our other information including variations, genotype and allele frequencies from dbSNP, and SNPs from other sources including UniProt, Affymetrix and Illumina chipsets and phenotype annotations from several genome-wide association studies.

You need to configure the page to view SNPedia. From the variation page, e.g. rs1333049, click on "Configure this page" and then click on "External Data" to select SNPedia to appear in the left hand side menu of all variation pages via DAS. As this information comes directly from SNPedia via DAS it is always up-to-date.

Eyjafjallajökulled?

This could be come a new word in English is it becomes more frequent... well whilst most of Europe was grounded (and some colleagues from Ensembl stranded throughout the world) we only had to postpone one workshop... And our tour of Australia continued (we only had domestic flights and these weren't disrupted), coming to an end this week (I'm flying to Canberra where the ANU is hosting the last of the series).

Great feedback (thanks for filling those surveys, guys!), and our SNP Effect Predictor tool is becoming very useful, this trip also gave us a a chance to test (first hand) the speed of access to the browser and API from Australia.

This coming month, as Bert has already posted, we are attending a couple of conferences in France, if you are attending the Paris workshop (it may not be too late to register if you plan to be in town) you will have to clear security (it's hosted at the UNESCO at the end of the day), so come early (with your passport or ID card), we are also running a workshop in Montepellier (thanks to HUGO and specially Cathy for this one).

Back to Europe soon,

Shortcut addresses for Ensembl versions

Want to be sure you are going to the right version of Ensembl? Whilst our archives can be accessed through the link at the bottom of each page, if you want to cite a particular version or access it directly, you previously needed to know the month and year of release to find the archive site (e.g. may2009.archive.ensembl.org).

Now, for the convenience of our users, we have introduced shortcuts that include the version number instead of the date. For example, typing:

e54.ensembl.org

into your browser will redirect you to the same May 2009 archive.

We have put these redirects in as far back as e30 - if the archive no longer exists, you will be directed to the next most recent one (unless doing so would mean a change of assembly, in which case you are redirected back to the last archive on your chosen assembly, if available).

P.S. Don't forget the 'e' at the beginning - we can't use plain numbers as it causes problems with DNS servers

¡ə Ensembl Down Under

Ensembl is running a series of workshops in Oz, starting today in Melbourne at the VLSCI (tomorrow we have a couple of seminars at the WEHI and Peter MacCallun). Later this week we will have a further workshop in Adelaide, to continue next week in Sydney, Brisbane and Canberra. So if you are in the area, why don't you come around?

Furthermore, we took this opportunity to finished the details of another coming workshop in Paris hosted by the Human Variome Project where in addition to Ensembl we will discuss other EBI resources such as EGA. There are still some seats available if you happen to be in Paris in May

Greetings from Melbourne.

Genomics and Transcriptomics in Mexico

As part of the EBI Roadshow training programme, Ensembl teamed up with ArrayExpress to run workshops for students, postdocs, and professors at ITESM, UNAM, and CIBNOR in these bioinformatic tools. The response was very positive. Feedback from 86 participants includes comments such as:

"I am an undergraduate student, and know little about bioinformatics. In the future, I will be able to use EBI as my primary resource."

"It is a really good opportunity to now get all these tools, to help facilitate understanding and analysis of scientific data"

"An excellent course, and very useful tools!"

Ensembl and ArrayExpress were ranked by 99% of participants as being useful to their work. Not only are people made more aware of individual projects through these workshops, EBI resources are publicised. 31% of our participants were unaware of EBI resources before the workshop, which contrasts to 95% responding that after this workshop, they would most likely use EBI resources. 88% of participants would like more training in these resources and others; specifically mentioned were ontologies, proteomics, and genome sequencing as topics to learn more about. This reflects a need for bioinformatics courses in the life sciences in that part of the world, if not in all the world.

And finally, an after-effect of the workshops was to prove that there is a lot of interest in bioinformatics. This from our host at CIBNOR:

"CIBNOR is in a growing stage, we have a project for an Innovation and Technology Park and I am trying to convince people about the need for a Bioinformatics Unit. I am sure that things like this course will help us a lot."

We greatly enjoyed training in Mexico, because of all the keen interest, energy, and the evenings on the sand dunes. We took the course into the field, discovering a pufferfish and spine on the beach, in honor of vertebrate genomes!

Orthologues on the trees


We have added a little trick for orthology-lovers. Starting from the orthologues page, you can choose to switch to the GeneTree. This will highlight the orthologue of interest, as well as the ancestral node that relates both genes.

Another useful feature added in Ensembl 57 is the possibility to display a set of genes (up to 10) using the Multi-Species view. Click on an internal node and select the "Jump to Multi-species view" option. This will show each of these genes in their respective genomic location, with genomic alignments when available.

New avian and new fish mutliple alignments



Ensembl 57 includes the turkey genome, the third bird in Ensembl. We are now providing a 3-way avian multiple alignments (chicken, turkey and zebra finch) together with GERP constraint analysis. The image shows amniote and bird constrained elements on the chicken genome.

We have also added a new set of fish multiple alignments (stickleback, medaka, takifugu, tetraodon and zebrafish). GERP constraint analysis is available on fish genomes as well.

10 March, 2010

Gene Trees now have intron ticks.


The gene tree images now have little intron "ticks" on them showing how the intron position is placed relative to the protein sequence. An example is shown above. Each tick is a little black line on each side of the green protein bars, on the right. As intron positions have been remarkably stable on the "chordate" side of the metazoan tree (ie, the deutrosomes), one should expect that the introns line up - if they do, it is good evidence that the alignment is right.

There are some interesting things. Ensembl models small frameshifts to create open reading frames around erroneous data as tiny introns. In this code you cannot distinguish these two classes of introns, but as these errors normally come in patches, a run of intron ticks unique to a genome is probably a set of errors (an example is in Gorilla). I've enjoyed browsing around some of my favourite genes to check out that the introns make sense.

There is some more to go here. The fact that the intron ticks disappear on collapsed nodes is a bit frustrating - it would be nice to see "consensus" intron positions (though this is a bit complex to execute underneath).

Calling all Americans (and Australians/NZ/Pacific Rim...)

For about 3 weeks now researchers in the US have had their default Ensembl go to our US west mirror (uswest.ensembl.org) automatically - if you just go to www.ensembl.org you brower gets automatically redirected. The US joined Japan and Canada who we switched in late 2009.

From our perspective, this is all working fine; the usage of uswest has gone up, and IP tracking on that shows far more US IP addresses (so the redirect is working fine!). We get some 3,000 odd visits a day, with some 50,000 pages delivered from our uswest site - about 20% of our total hits. Brilliant.

What is slightly more surprising is that we're not getting any queries on this. Given the usage, we think this means the default browser, content and other functionality must be working well (or Americans are very shy about complaining... but that doesn't sound like a good description of all Americans...). But we'd also like to hear from American users - have you noticed ensembl "go faster?". Are there any glitches?

Another issue we are unclear about is whether we should automatically shift other users on the Pacific Rim to automatically go to uswest - in terms of usage, the biggest country would be Australia, but New Zealand, Phillipines and other Pacific Rim countries would also be candidates. It's quite hard for us to assess whether our Europe (Cambridge UK) based servers or US west servers are best for this - both latency and throughput changes on different routes, and the time zone shift makes things complex to assess systematically in an easy way.


So - feedback welcome - either on this post or to helpdesk@ensembl.org about what your experience is, either from the US or from the pacific rim.
