What’s new in e83:

  • Human: gene set updated to GENCODE 24, and new assembly patches (GRCh38.p5)
  • Manhattan plot track for LD
  • Advanced Filtering and Counts on Variant table
  • Minor allele frequency (MAF) filter on sequence mark-up views

Human gene set update and new assembly patches

chromosome_exceptions

The human gene set now corresponds to GENCODE 24 while the assembly has been updated to include new assembly patches for GRCh38.p5.

Manhattan plot track for linkage disequilibrium

This new linkage disequilibrium (LD) track is focused on a variant and displays the linked variants surrounding the focus variant. The track displays a Manhattan plot, using the r2 and D prime values (from 0 to 1) on the Y axis. The new track is accessible in the Variation Linkage disequilibrium page, through the links in the new column “LD Manhattan plot“.

Manhattan_plot_track_LD

Advanced Filtering and Counts on Variant table

The functionality of the variant table has been further expanded to allow a wider range of filtering options. Filtering can now be applied by Minor Allele Frequency, SIFT and PolyPhen scores, Clinical Significance, Consequence Type and many other columns, using buttons along the top of the variant table. For many of these filters, preset useful combinations of options are available within the popup allowing rapid configuration of more complex combinations. In addition, row counts for each consequence type have been readded to the existing Consequence Type filter. These are displayed in the popup which appears once the filter button has been pressed.

MAF filter on sequence mark-up views

The variants displayed on all sequence mark-up views can be filtered by minor allele frequency (MAF), allowing you to either show or hide according to a range of frequencies (between 0.01% and 10%). This filtering is not on by default so to enable it go to ‘Configure this page’ on any sequence view page and then choose the value you want from the ‘Hide variants by frequency (MAF)’ drop down menu.

Support of VEP Plugins through the web interface, script and REST

The VEP can now be extended beyond its core functionality using a system of plugins. Plugins are a powerful way to extend, filter and manipulate the output of the VEP. More information regarding the VEP plugins can be found on the following documentation page.

Improved Variation tables

Variation tables for genes and transcripts have been reimplemented to effectively handle the large number of variants now known for many genes. At the same time, the ability to filter, sort, and select this data has been improved. Filtering by variant type is now achieved by selecting the “Type:” filter at the top of the main table. Further features and refinements are expected to be added in forthcoming releases.

Zebrafish development stage RNASeq data set

We’ve added sample-specific BAM files, splice junctions (introns) and gene models based on a range of zebrafish developmental stages and tissue samples.

Zebrafish_BAM_track

Marking a region on images

A new feature to mark a selected region has been added to the location, gene and other views. Marking can be applied by drag-selecting a region and then using the zmenu to mark it, or by clicking on a feature on an image and then using the zmenu to mark the location of the feature.

LastZ replaced TBlat for pairwise alignments

We have replaced TBlat with LastZ and recomputed 9 pairwise alignments using LastZ. TBlat was used for distantly related species as it was yielding a higher genome coverage, but over time we have optimised the LastZ parameters that enable it to give a 50-100% increase in genome coverage.

Track label improvement

Some tracks in images now appear within sections, grouping common tracks within a category is now possible.

Each section is identified by a heading underlined in a certain colour, and each track within that section using the same colour on the left-hand side.

Also, some tracks now have labels within the image itself, to allow longer descriptions. These in-image labels can be configured on or off via the configuration panel.

New user data track type: long-range interactions

We are very pleased to announce that Ensembl now supports long-range pairwise interaction data, which can be drawn as arcs on Region in Detail. Scores are indicated using a grey-to-black gradient, and labels can be displayed by selecting the appropriate track style from the configuration menu.

Initially we support the two formats developed by WashU for their Epigenomics browser. More information on both formats can be found in our online documentation.

We hope to support more formats in the future, so please let us know which formats you are currently using!

After running our brand new Ensembl Regulatory Build on the human GRCh38 and GRCh37 assemblies, we spent some time revamping our current Regulation mart to make it faster, easier to use and pack it with brand new features. A complete re-design of the mart has been done in the background to make sure our mart can provide improved performance and deal with the data increase. The new Regulation mart can still be found on the Ensembl website under the BioMart tab.

The first thing that you will notice is that you can now access each regulation data type separately, this allows you to get the data quickly and make the filter and attribute sections neater.

What’s new in e!77?

Imported Transcript Support Levels (TSLs) from UCSC

Transcript Support Levels (TSLs)We have imported Transcript Support Levels (TSLs) from UCSC and we are displaying them as a new flag in the human and mouse Gene and Transcript tables. TSLs for human are based on the GENCODE 20 gene set and TSLs for mouse are based on the GENCODE M2 gene set. Transcript Support Level is a method to highlight the well-supported and poorly-supported transcript models for users.

New APPRIS flag for human and mouse

APPRIS principal isoformWe’ve added a new flag for human and mouse in the Gene and Transcript tables  to represent the principal isoform generated by APPRIS which is a system that deploys a range of computational methods to provide value to the annotations of the human genome. It aims to select a single CDS for each gene as the principal isoform by combining protein structural information, functionally important residues and evidence from cross-species alignments. APPRIS is a joint project between Centro Nacional de Investigaciones Oncologicas and Instituto Nacional de Bioinformatica.

Improved alignments export

New alignment export toolThis release we are continuing our upgrade of our Export interface, the second component to be released is the alignments. To download an alignment, just navigate to one of the following pages:

Select an alignment, click on the “Download sequence” button, select your favourite output format from CLUSTALW, FASTA, Mega, MSF, Nexus, Pfam, Phylip, PSI, RTF (text alignment views only) or Stockholm, preview the output file, and save it.

New species

Chlorocebus_sabaeusThe Vervet-AGM (Chlorocebus sabaeus), also known as the Vervet Monkey or African Green Monkey, ChlSab1.1 (GCA_000409795.2), was produced by the Vervet Genomics Consortium. This species is particularly important when studying high blood pressure and AIDS, since it is a host for simian immunodeficiency virus (SIV). BAM files and RNAseq-based gene models are available also for this species.

Other news:

  • Data matrix configuration extended to all species with RNASeq data
  • Added new studies and updated other studies for human from DGVa
  • Updated human phenotype from ClinVar and Decipher

What’s new in e!76?

New human assembly – GRCh38

GRCh38We’re excited to release the full annotation of the new human genome assembly (GRCh38). This new assembly includes 24 chromosomes, mitochondrial DNA, 261 alternative reference loci, 127 unplaced scaffolds and 42 unlocalized scaffolds. Our comprehensive GRCh38 resources include updated variation data, results from the new regulatory annotation build, updated comparative genomics data and tissue-specific alignments of Human BodyMap 2.0 data. Full details in our GRCh38 blog series.

There are many reasons to switch to the new human assembly, but if you not able to move just yet, our new archive website http://grch37.ensembl.org provides access to the previous assembly and annotation for those who need it.

New BLAST/BLAT

New BLAST Karyotype view

Release 76 includes our new BLAST/BLAT, which uses the same tools infrastructure as the new web-based VEP that came out in release 75. Highlights of this new version includes the ability to save tickets in a user-friendly table, automatic result retrieval, improved speed and job tracking. We are also now using NCBI-BLAST to enable us to distribute our BLAST code more freely.

New Regulation displays

regulation-display

 

 

 

 

 

 

The display of regulatory regions (sequences that may be involved in gene regulation) has been updated to coincide with the release of the data from the new Ensembl Regulatory build. The major enhancement is a redesigned interface for selecting which evidence types to display and for which cell types, as well as how to display the evidence, for example as peaks or signals.

More details about the new regulation pipeline and displays can be found on the Regulatory Build documentation.

Improved sequence export

new_export_toolWe are embarking on an upgrade of our Export interface to make it more intuitive; the first component to be released is DNA and peptide sequences. To download a sequence, just navigate to a sequence page, click on the “Download sequence” button, select your favourite output format, preview the output file and save it. Note that the “Export data” button has been disabled on pages that use this new interface, to avoid confusion.

New species

We are happy to announce annotation for two new species in this release.

Papio_anubis

The Olive baboon (Papio anubis) assembly, Panu_2.0 (GCA_000264685.1) was produced by the Baylor College of Medicine. This species is used for physiological and behavioural studies as well as comparative genomic studies. BAM files and RNA-seq based gene models are provided through a collaboration between the Nonhuman Primate Reference Transcriptome Resource (nhprtr.org) and the Human Genome Sequencing Center, Baylor College of Medicine (hgsc.bcm.edu).

Amazon molly

The Amazon molly (Poecilia formosa) assembly, Poecilia_formosa-5.1.2 (GCA_000485575.1) was produced by the Aquatic Genome Models Consortium. Amazon molly is used as a model for modern evolutionary biology and carcinogenicity studies, and is extremely easy to breed and rear in captivity. More information on the Amazon molly blog post.
