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

Transcription Factor Binding sites

The modENCODE Transcription Factor data has been added as 321,212 new
Feature objects with the Method tag 'TF_binding_site_region'.  This
data was derived from the Snyder Lab project to map the binding sites
of a selection of transcription factors in various life-stages and
conditions using ChIP-Seq.

The region where the transcription factor binds has been called by
modENCODE using peak-finding software on the ChIP-Seq results, the
binding sites are therefore currently known only approximately,
typically in a region of about 200 bases, or larger.

These data have a GFF line with the "type" column containing the SO
term 'TF_binding_site' and with the name of the transcription factor
and the ID of the transcription factor object in the database, for
example:


CHROMOSOME_III  TF_binding_site_region  TF_binding_site 14696   15618   .       +       .       Feature "WBsf401679" ; TF_ID "WBTranscriptionFactor000025" ; TF_name "DAF-16"

Where binding sites are known exactly, the Feature object's Method tag
will be changed to 'TF_binding_site'. There are some existing exactly
known sites, from other projects, having Feature objects with the
Method tag 'TF_binding_site'.




Genome Sequence error sites


Features marking known genome sequence error locations that have
already been corrected by changing the C. elegans reference genome
sequence now have the Method tag 'Corrected_genome_sequence_error'.

These have a GFF line with the "type" column containing the SO term
'base_call_error_correction', for example:

CHROMOSOME_III  RNASeq  base_call_error_correction      661017  661017  .       +       .       Feature "WBsf047774"


We have been working on marking possible genome sequence errors in the
C. elegans reference genome using data from the following projects:


- Weber KP et al. (2010) PLoS One "Whole genome sequencing highlights
  genetic changes associated with laboratory ...."

PMID 21085631

- Doitsidou M et al. (2010) PLoS One "C. elegans mutant identification
  with a one-step whole-genome-sequencing and ...."

PMID 21079745

- McGrath PT et al. (2011) Nature "Parallel evolution of domesticated
  Caenorhabditis species targets pheromone ...."

PMID 21849976

This data has been used to create Feature objects with a Method tag of
'Genome_sequence_error', taking the total of these locations in the
C. elegans database to 2,428.

These data have a GFF line with the "type" column containing the SO
term 'possible_base_call_error', for example:


CHROMOSOME_III  RNASeq  possible_base_call_error        38559   38560   .       +       .       Feature "WBsf268625"


No changes have been made yet to the C. elegans reference genome
sequence to correct these locations. We intend to correct the sites
that can be shown to influence coding genes in a future release of
WormBase. There are 77 indel errors in the C. elegans genome that
affect the structure of a coding gene.

There are two possible error sites on the C. elegans mitochondrial
sequence.  As the WormBase consortium does not own the mitochondrial
sequence, we will mark these sites with a Feature object with the
Method tag 'Genome_sequence_error', but we will not be changing this
sequence.


Genome sequence updates:
-----------------------

None this release

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


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


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

The life-cycle data in all objects has been changed from being held as
the name of the life-cycle stage to the ID number of the life-cycle
stage.

For example: 'L1 larva' has been changed to be held as the ID
'WBls:0000024' in all objects that refer to it.


Model Changes:

In this release there are changes to a number of classes:

?Strain

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.
