New web displays and tools
BigWig Manhattan plots (all species)
In this release, we've added the ability to display your bigWig data as a Manhattan plot:
Simply select 'Manhattan plot' from the track style list after loading.
Orthologue Table redesign (all species)
The orthologue table has been redesigned slightly with the aim of inproving usability. It also accomodates three new metrics representing the confidence of our ortholgue predictions - Gene Order Conservation (GOC) Score, Whole Genome Alignment (WGA) Coverage, and High Confidence.
Variation track style consolidation (all species)
The code for drawing our SNP and indel variation tracks has been consolidated so that tracks will appear the same across all views.
Summary of changes
- Deletions are drawn as a block spanning the deleted area, with the addition of a downwards-pointing triangle symbol superimposed.
- Insertions are drawn the same way as before, but are enlarged at smaller scales for better visibility
- Variation tracks on Protein Summary are drawn the same way as on other images, instead of as tiny squares and triangles, and can thus be configured as different styles, eg. with labels
In addition to the visual changes, we have also fixed some bugs with variant placement on Protein Summary.
New comparative genomic views for strains (all species)
The mouse strains resources (mouse reference assembly, mouse strains and rat reference assembly) have a separate left hand menu for their own comparative genomics resources which includes gene trees, orthologues and paralogues.
New species selector (all species)
New species selector user interface designed for Blast, Region Comparison and Alignment Selector with below features.
- Division based species selection
- Add/remove/sort species
Mouse strain variant table (Mouse)
A new location display, "Strain table", visible for Mouse location displays, shows variants between mouse strains within the region in a tabular form.
GTEx beta value display (Human)
The GTEx per-tissue variant expression data for genes can now be configured to display beta-distribution values, instead of log-p-value figures. This is configured by altering the track renderers. These tracks have also been moved out of "Other regulatory regions" into their own section, directly under the general Regulation heading.
New species, assemblies and genebuilds
Mouse Strains (all species)
Annotation and assemblies for 16 mice, produced by the Mouse Genomes Project, have been added. De novo assemblies for each strain were built from a mixture of short- and long-range illumina libraries, optical maps, and third generation sequencing. Genes were annotated primarily by projection of the GENCODE gene set from GRCm38 to each strain. The projected annotation was refined with strain-specific RNA-seq data. The RNA-seq data were also used to find novel annotations.
We have annotationed additional genomic features including: repeats, CpG islands, predicted promotor regions and BLAST alignments of UniProt proteins. We have also annotated protein domains using InterProScan.
The collection comprises of one outgroup mouse (Mus spretus), three Mus musculus subspecies (castaneus, musculus and domesticus) and twelve strains of Mus musculus. The full list can be seen below:
Mus musculus 129S1/SvImJ
Mus musculus A/J
Mus musculus AKR/J
Mus musculus BALB/cJ
Mus musculus C3H/HeJ
Mus musculus C57BL/6NJ

Zebrafish: updated RefSeq gene import (Zebrafish)
The imported RefSeq gene set was updated in the zebrafish otherfeatures database. Please note that RefSeq annotates gene models on cDNA sequence and not on the reference genome, meaning that when users choose to translate the RefSeq transcripts off the reference genome that the translations may contain stop codons.
Human: updated RefSeq gene import (Human)
The imported RefSeq gene set was updated in the human otherfeatures database. Please note that RefSeq annotates gene models on cDNA sequence and not on the reference genome, meaning that when users choose to translate the RefSeq transcripts off the reference genome that the translations may contain stop codons.
Mouse: updated RefSeq gene import (Mouse)
The imported RefSeq gene set was updated in the mouse otherfeatures database. Please note that RefSeq annotates gene models on cDNA sequence and not on the reference genome, meaning that when users choose to translate the RefSeq transcripts off the reference genome that the translations may contain stop codons.
Human/mouse/zebrafish: Ensembl-to-RefSeq comparison attributes (Zebrafish, Human, Mouse)
For each Ensembl transcript present in the human and mouse core db, a comparison is carried out with all overlapping RefSeq transcripts from the otherfeatures db.
Up to five comparisons are carried out (depending on if the models are non-coding or coding):
1) Check if all exons coordinates match (all transcripts)
2) Check if transcript sequences match (all transcripts)
3) Check if the CDS exon coordinates match (coding transcripts only)
4) Check if the CDS sequences match (coding transcripts only)
5) Check if the translation sequences match (coding transcripts only)
For non-coding models, if comparisons (1) and (2) are a match then the transcripts are considered to match on the whole transcript level and the Ensembl transcript is given an attribute to say there is a match on the whole transcript level.
For coding models if all five comparisons are true then the Ensembl transcript is given an attribute to say there is a match on the whole transcript level. Failing that, if comparisons (3), (4) and (5) are true the Ensembl transcript is given an attribute to say there is a match on the whole transcript level.
The stable ids of any matching RefSeq transcripts will be stored in the value field of the Ensembl transcript attribute.
Mouse lemur otherfeatures database (Mouse Lemur)
A new gene set for the mouse lemur assembly, Mmur2.0, requires new core, rnaseq and otherfeatures databases. Species-specific ESTs and cDNAs were aligned to the genome and alignments are available through the website or otherfeatures database.
Chicken otherfeatures database (Chicken)
A new genebuild on the chicken assembly, Gallus_gallus-5.0, requires chicken core, rnaseq and otherfeatures databases. Chicken-specific cDNAs and ESTs were aligned to the chicken genome and are made available through the Ensembl website and the chicken otherfeatures database.
Chicken RNAseq and Bam files (Chicken)
In addition to the gene annotation for Galgal_5.0, an rnaseq database will be released where users can view BAM files and transcript models for different tissues.
Macaque otherfeatures database (Macaque)
A new genebuild on the macaque assembly, Mmul_8.0.1, requires macaque core, rnaseq and otherfeatures databases. Macaque-specific cDNAs and ESTs were aligned to the macaque genome and are made available through the Ensembl website and the macaque otherfeatures database.

In addition to the gene annotation for macaque, an rnaseq database will be released where users can view BAM files and transcript models for different tissues.

Updated mouse otherfeatures db: New CCDS import (Mouse)
This release of the mouse gene set also includes 24,826 transcript models as part of an updated version (July 2016) of CCDS
Human: transcript attributes for Refseq-genomic-to-mRNA comparison (Human)
Transcript attributes will be added for the refseq_import geneset in the human otherfeatures db. Each refseq_import transcript will have an attribute to denote whether the genomic sequence that the transcript covers matches the mRNA sequence that the transcript is based on (the sequences present in the RefSeq mRNA file).
A prefect match is denoted as an alignment across the entirety of both sequences that contains no mismatches or indels. If initially there is a mismatch, the RefSeq mRNA will go through polyA clipping and the sequences will be compared again to see if a perfect match is possible post polyA clipping.
Transcripts that do not have a perfect match between the mRNA and the genomic sequence will get additional attributes to define what regions (5' UTR, CDS, 3' UTR, or 'whole transcript' if there is no CDS defined) do not align perfectly, along with a summary of the information in the alignment (match,mismatch, indel count, total indel length).

Further description can be found on GitHub

By deafult, only reference mouse hits are shown. By faceting on mouse, all hits on strains are also shown, along with a further faceting option to refine that selection.
Retirement of archive 73 (all species)
This release cycle we will be retiring archive 73 (September 2013) in accordance with our three-year rolling retirement policy. The data will remain available on our public database server; only the web interface will be removed.
