New Data:
The C.japonica genome sequence and annotation are included in this release. 
Gene predictions are from the nGASP project.
The standard set proteins sets have been blasted against the genome sequence and proteome.
Protein annotation with PFAM and InterPro domains etc is included.
Orthologies with other nematodes has been determined using the COMPARA analysis method and gene names transfered where appropriate.
C.japonica is also included in the multigenome alignments available from the FTP site.

Genome sequence updates:

New Fixes:
A problem with CDSs that have more that one coding_transcipt being appearing as non-coding genes in the genome browser has been fixed.  This was patched for WS194

Known Problems:

Other Changes:

Proposed Changes / Forthcoming Data:
The C.brenneri genome will be included in WS196

Model Changes:

added confidence info to ?Interaction

fixed typo in ?Strain  Phenotype_info


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.

  • as some C.elegans proteins in the Inparanoid6 XML files errouneoulsy specify Homo sapiens, some "dodgy" human proteins were created
  • the patch should correct the ids, merge them into the C.elegans proteins and fix the Species + EnsEMBL xrefs
