.. class:: infomark

**What it does**

Adds a CEAS gene annotation table file to the *ceas_annotations"* data table. The
database file can be downloaded from the CEAS website, imported from a file on the
Galaxy server, or generated from a ``wig`` file in a Galaxy history.

**Notice:** If you leave the identifier or description blank then they will be
generated automatically.

.. class:: infomark

**Fetching, uploading or creating gene annotation table files**

The gene annotation table files are SQLite database files which are on the CEAS website:

 - http://liulab.dfci.harvard.edu/CEAS/usermanual.html

The data manager allows you to fetch a pre-built table from the CEAS website; note
that these are based on the ``RefSeq`` annotation and are only available for a subset
of genome builds.

To create an annotation table for a different genome build or a different annotation,
use the *Generated from wig* file option. This runs the CEAS utility ``build_genomeBG``
to make a custom table from a wig file, which represents the genome background (e.g.
a wig file created from the ``control lambda`` bedgraph file output from MACS2).

Alternatively if you already have an existing custom annotation file then this can be
imported from a path on the Galaxy server.
