gene DAS tracks

2006-08-01T15:43:04Z

You might have noticed that you can make Vega genes visible in Ensembl now and vice versa using DAS tracks. In order to switch Vega genes on in Ensembl, go to 'DAS sources' and check 'Vega Transcripts' (example). To see Ensembl genes in Vega, check 'Ensembl Transcripts' (example). Please note that this only includes genes that were annotated in Vega so far on clones that are present in both databases. We are currently working on transferring also genes that are e.g. in Zv6 scaffolds.

change to fpc database

2004-09-27T10:51:01Z

The zebrafish fpc map, released via WebFPC on the 19th September 2004, uses externally recognised clone names in the display e.g. DKEY-110K5, instead of internal Sanger Institute clone names e.g. zK110K5. In order to ease any problems the transition may cause, the existing version of WebFPC will remain in place until November the 1st and additionally the clone search will continue to accept searches for clones in either naming format.

Fluorescence In Situ Hybridisation

2004-08-13T09:32:40Z

In collaboration with Dr. Charles Lee at Brigham and Women's Hospital, Boston, and with the Sanger Cytogenetics group we have begun to place contigs onto the genome using Fluorescent In Situ Hybridisation (FISH) on metaphase spreads of chromosomes derived from embryo tissue. We hope to define chromosomal locations for many of the unplaced contigs this way. Gap sizes between anchored contigs can be determined using fibre FISH. An improving view of the cytogenetics of the Zebrafish will enable more accurate chromosome sizing and identification.

FPC database modification

2004-05-10T13:38:05Z

The FPC database will undergo a noteworthy change with the next version (to be released in 2-3 weeks). We have re-numbered the FPC contigs with the aim of simplifing our merging process. With the next release we will provide a conversion file listing the old contig and new contig number for each clone. As with previous versions the contig numbers will continue to change as the database develops, it is therefore advisable to use clone names/accessions to follow particular regions/sequences.

two computer biologists wanted

2004-04-30T14:38:58Z

We have two positions available to work on the ZF models project. For details please check the job advertisement and the ZF-models homepage.

ensembl news

2004-04-01T12:27:12Z

From today onwards, the ensembl releases are based on a different way of storing the sequence. You will see this on the contigview pages, they don't display names like ctg30.1, ctg30.2, etc. anymore. Instead this will all be ctg30, but if you move your mouse over the sequence, it will offer you to export either the whole supercontig or just the current 'chunk', e.g. what used to be ctg30.2. The new ensembl release also features translated BLAT comparisons to the human genome now ('HS trans BLAT' under 'compara' option on contigview).

Zv2 data wanted?

2004-02-26T18:16:24Z

In case you're interested in Zv2 data and haven't saved them in time before the Zv3 ensembl was released: You can still access the old Zv2 ensembl data dumps.

mapping data

2004-02-20T17:13:40Z

Pre-Ensembl Zebrafish database

2003-04-03T13:10:02Z

CAVEAT

The assembly couldn't be tied to a map, therefore comes in 83470 individual non-connected supercontigs. For internal reasons these were randomly put together into 363 assembly chunks of a size of roughly 5Mb. A gap of 5kb was inserted in between each neighbouring supercontig to make them distinguishable. Please look out for these 5kb gaps and don't assume that sequence on either side belongs together.
