.. class:: infomark

GOEnrichment is a Java application that can be used to analyze gene product sets (e.g., from microarray or RNAseq experiments) for enriched GO terms.

-----

.. class:: infomark

GOEnrichment requires:

- A Gene Ontology file in either OBO or OWL format (see http://geneontology.org/page/download-ontology).
- A tabular annotation file in GAF (http://geneontology.org/page/download-annotations) format, BLAST2GO format, or a simple two-column table (e.g. from BioMart) with gene product ids in the first column and GO terms in the second one.
- A list of gene products comprising the study set (a flat text file with one gene product per line).
- Optionally, a list of gene products comprising the population set (if none is submitted, the population set will be the set of gene products listed in the annotation file).

-----

.. class:: infomark

GOEnrichment produces a tabular result file and a graph file for each GO type (MF - Molecular Function, BP - Biological Process and CC - Cellular Component):

- The result file is a tabular list of all GO terms present in the study set and their respective p-values.
- The graph file can be either a png image, an svg image, or a text file for importing into cytoscape (together with the result file).

-----

.. class:: infomark

The graph is colored by p-value: terms with p-value above cut-off appear in white; and the color gets darker as the p-value decreases

.. image:: https://github.com/DanFaria/GOEnrichment/raw/master/Scale.png
   :width: 600
   :height: 315

(see the scale at https://github.com/DanFaria/GOEnrichment/blob/master/Scale.png). In addition to the name of each GO term, the graph
shows its frequency in the study set. Dashed edges indicate that one or more intermediate terms were ommited from the graph.

-----

.. class:: warningmark

Gene products listed in either the study or population set files that are not present in the annotation file will be ignored.
