New Data:
---------
The SAGE analysis from Jones et al has been incorporated into this release. There
are approximately 35,000 SAGE tags in the dataset.
Marker loci on the genetic map have been partioned into those which have been
experimentally defined (displayed in yellow) and those which are computationally
inferred (displayed in orange).
New Fixes:
----------
Known Problems:
--------------
Other Changes:
--------------
The script that check overlaps between coding exons and repeat sequences now uses
the RepeatMasker data. Hence, the numbers have increased significantly. There are
two caveats to these numbers; Firstly, at the moment these include the low-complexity
mark up of RepeatMasker which we will in future ignore, this will reduce the numbers
by approximately a third. Secondly, the latest RepeatMasker library still contains
some motifs from multiple-gene families and hence overestimates the number of genes
which need attention. The curators will work through this list to remove these motifs
from the repeat library.
Proposed Changes / Forthcoming Data:

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 www.acedb.org).
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.
