Ensembl release 20 incorporates a major redesign of the Ensembl core
schema and API. There are no new genome assemblies or gene builds in this release.
No data updates other than port to new schema.
Lite database
Lite database removed.
Compara database
- New protein clustering and families
- New BLAT alignments from UCSC
- Addition of N, S and LnL data and schema
- Storage of dS cut-off value in the db
- Updated blastz alignments to take in account GroupId and LevelId
- Corrected synteny data

Schema changes in v20 |
|
|
|
|
|
Core database
Details of the new core schema and API can be found in the wiki.
Lite
As a result of the core schema and API changes, the lite database now only
contains SNP information. If a species has no SNP database (e.g. C.briggsae)
that species will also have no lite database.
SNP database
- GTInd table added to hold individual genotype data
- Strain table has new columns ssid and ind_id
Compara database
- genomic_align_block table has new columns group_id, level_id and flip_alignment
- homology table added

|
|
|

Nearly all of the work on the webcode for this release has been modifying it to
work with the new v20 API. Other changes include:
ContigView
BLAT tracks added for the new Compara data
|
|
|
SNPView
Where available, the following data have been added to the display:
- Allele frequencies, per SubSNP/population/assay
- Strain genotypes
