New Data:
Jack Chen that his group have generated genome-wide predictions for protein-coding genes in briggsae, remanei, brenneri, and japonica. These are based on the homologous C. elegans genes.

This data is produced by the genBlastG program which is a development of the genBlastA program:

Nota Bene that these data are being provided in advance of publication of the five-genome paper (coordinated by Erich Schwartz).

ncRNA entries were extended to include primary as well as mature transcripts and updated using mirbase and RFAM.

Genome sequence updates:

New Fixes:

Known Problems:
Some RNAi mappings are a bit erratic. A fix will be forthcoming.
Some Gene Ontology terms are outdated (update planned for WS214)

Other Changes:

Proposed Changes / Forthcoming Data:
The Gene Ontology used by WormBase will be updated for WS214
The Journal class will be removed with WS214, as it's functionality is covered by other classes.

Model Changes:
the planned removal of the Journal class is postponed until WS214


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.
