 New Data:
 The following databases were updated for BLAST:
 trembl release 35
 swissprot release 52
 Genome sequence updates:
 New Fixes:
 Known Problems:
 Other Changes:
 Many Poly-A tails were masked in EST and mRNA sequences.  New Poly-A
 Site and Poly-A Signal sequence Features were defined based on the
 alignment of these sequences to the genome:
 - 3530 new (1931 site, 1599 signal sequence) Features were defined.
 - 641 old Poly-A Features (490 site, 151 signal) with no supporting
   Sequence evidence were removed (changed to Method="history").
 Proposed Changes / Forthcoming Data:
 We are working with the authors of this paper:
 Ruby J et al. Cell. 2006 Dec 15;127(6):1193-207.  "Large-scale
 sequencing reveals 21U-RNAs and additional microRNAs and endogenous
 siRNAs in C. elegans.";class=Paper
 to refine and annotate circa 4500 new elegans RNA genes.
 <A third class of nematode small RNAs, called 21U-RNAs, was
 discovered. 21U-RNAs are precisely 21 nucleotides long, begin with a
 uridine 5''-monophosphate but are diverse in their remaining 20
 nucleotides, and appear modified at their 3''-terminal
 ribose. 21U-RNAs originate from more than 5700 genomic loci dispersed
 in two broad regions of chromosome IV-primarily between protein-coding
 genes or within their introns. These loci share a large upstream motif
 that enables accurate prediction of additional 21U-RNAs. The motif is
 conserved in other nematodes, presumably because of its importance for
 producing these diverse, autonomously expressed, small RNAs
 Forthcoming model changes:
 Added tags to ?Person and ?Paper to enable recording of negative
 connections ie Mr X did NOT contribue to this paper.
 Added Map_evidence to ?Transgene so that the paper that mapping data
 is taken from can be attributed
 Added a tags to ?Expr_pattern and ?Expression_cluster to handle
 Localizome data Note: ?Interaction class update already committed
 Model Changes:
 Added DB_info line to ?Gene
 Replaced ?Y2H with a more generic ?YH class which contains Y2H and Y1H
 Added Anatomy_function class to allow the connection between
 ?Anatomy_term, ?Phenotype (proxy of biological function), and ?Gene
 and still give some information about the experiment itself. Name
 shall be "WBbtf0001"
 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.
