Data sets coming from high throughput experiments which reside in SPELL have now been updated with topics so that you can actually search by your favorite topic. You can see the topic search options by clicking the button ‘Options for Filtering Results by Dataset Tags‘ on the SPELL home page under the search box for Gene Name(s).
We are pleased to introduce a new genome browser that we are currently testing as a replacement for the current, long serving genome browser (GBrowse). The new browser, an implementation of JBrowse from the GMOD project, is currently available at wormbase.org/tools/genome/jbrowse/. The new genome browser has a fast and pliable user interface; becoming oriented to the new browser should be relatively painless as it shares many design features in common with the current browser.
The new genome browser also has new functionality not available in the old one. Key among these are (all of which are available from the genome browser’s file menu):
- Opening many types of data files (GFF, BAM, BigWig/BigBed, VCF), without having to upload them (so it’s *fast*).
- Creating combination tracks, where the contents of any two tracks can be combined using set or arithmetic operations.
- Making a sequence (DNA or amino acid) search track that will highlight when a motif is present (the search string can take the form of regular expressions–please let us know if you’d like help writing a regular expression).
Other useful features include the ability to “pin” a track to the top of the browser so it won’t scroll off the top of the page (simplifying visual comparisons with other open tracks), and a “full page” button that will open a new browser window where the genome browser takes up the full page.
Please try out the new browser and give us any feedback you can think of, either things you’d like to see, things you don’t like, whatever.
The newly released WS248 version of WormBase includes several updates based on curation topics as well as synchronisation with other databases.
In addition the use of Gene Ontology has been extended.
microRNA update for Brugia malayi
The newest data on Brugia malayi microRNAs from miRBase Release 21 has been integrated,
which includes pre-miRNA and mature transcripts as well as the consolidation of
nomenclature used by WormBase and miRBase.
Heavy Metal Topic curation
This release focuses on the curation of data related to Heavy Metal response in nematodes.
Supporting data and publications have been added to WormBase, in addition to review of
gene models for genes involved in this pathway.
New automated descriptions
Gene descriptions generated automatically using a new in-house pipeline were rolled out
for C. elegans in the WS247 release. This release extends that to all other core
species (B. malayi, O. volvulus, C. briggsae, C. brenneri, C. remanei, C. japonica)
New Gene Ontology Annotation Class
Starting with the WS248 release, Gene Ontology annotations will be represented in a new class,
GO_annotation. The GO_annotation class modelsGO annotations as distinct objects in the
database and allows for richer representation of GO data. For example, the GO_annotation
class contains information on interacting genes for annotations that use the IGI (Inferred
from Genetic Interaction) and IPI (Inferred from Physical Interaction) evidence codes, and
also contains annotation extensions that provide additional context for GO terms, such as
substrates for enzymatic activities. The GO_annotation class also includes annotations from
external groups such as UniProt and the Gene Ontology Consortium’s phylogenetic annotation
efforts using PAINT.
