New Data:
---------

This release contains the ?Pseudogene class. This is another step on the path
to the right reverent new gene model.

Transcript objects for all gene predictions with EST/OST/mRNA data are 
generated as part of the build. These objects represent our closest guess
to the primary transcript object, spliced UTRs and CDS sequence. 


New Fixes:
----------


Known Problems:
--------------

Issues with the ?Pseudogene class in terms on mapping scripts. Many of the 
cross-reference between RNAi/PCR_products to pseudogenes have been lost due
to the move from the ?Sequence class to the ?Pseudogene class. These have 
been resolved in the WormBase scripts and will be corrected for the next
release.

The connection between a protein-coding ?Sequence object and the ?Transcript
object is explicitly only one way in WS108. This requires a model change and 
code amendments to correct the acefile.

Other Changes:
--------------

Proposed Changes / Forthcoming Data:
------------------------------------

Corrections for RNAi, PCR_product & interpolated_map_position mappings to
handle the ?Pseudogene class.

Change to the models to correctly handle CDS - Transcript connections.

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.
