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.

known bugs

confirmed introns

There seems to be a systematic 12bp shift in the confirmed intron features coming from RNAseq data - Removed for WS217

None of the Transcript confirmed intron data was processed for this build. - Resolved for WS217

missing C.remanei genes

There are three C.remanei CDSes that are missing gene ids


there are errors in the C.elegans AGP file (clones being out of sync with the public repositories), which will be solved in WS217.
