New Data:
The C.briggsae database has been rebuilt with some updated gene structures, orthology predictions and protein/transcript alignments.

Pristionchus pacificus is included for the first time including gene predictions imported from Ralf Sommer's group (paper in press).  We have 
calculated orthologies to C.elegans and transfered gene names where appropriate.

Genome sequence updates:

Other Changes:

Proposed Changes / Forthcoming Data:
C. japonica will be included in WS195, which will be the next frozen release.

We are working on calculating base pair conservation scores (using GERP) between the caenorhabditidae sp. elegans, briggsae, remanei, brenneri, and 
with Brugia malayi as an outgroup.  These are based on genome alignments and should be included in the near future.

Model Changes:
Add a 'Non_directional' tag to the #Interaction_info hash, which will be used to list genes that are involved in non-directional interactions (e.g. 

Add to ?Evidence:
Mass_spec_evidence ?Mass_spec_peptide

Connect ?Strain and ?Phenotype

Add Name and Other_name to ?Feature

Change Gene.Ortholog_other to use Protein object rather than accessions

?Transgene changes to allow curation of transgene markers.


Quick installation guide for UNIX/Linux systems

1. Create a new directory to contain your copy of WormBase,
	e.g. /users/yourname/wormbase

2. Unpack and untar all of the database.*.tar.gz files into
	this directory. You will need approximately 2-3 Gb of disk space.

3. Obtain and install a suitable acedb binary for your system
	(available from

4. Use the acedb 'xace' program to open your database, e.g.
	type 'xace /users/yourname/wormbase' at the command prompt.

5. See the acedb website for more information about acedb and
	using xace.

Protein Patches

Some data for proteins was missing (history,etc), the missing data can be found here for pristionchus and remanei.

Peptide Patches

The briggsae proteins were missing their peptide sequences, which can be found here
