Gene annotation including gene ontology terms associated with the uploaded genes will be returned. (To show associated gene ontology terms go into the show/hide options at the top of the page and select the relevant columns to display - this is not necessary for the ORA tool).
To do the gene ontology ORA click on the red Ontology
ORA button at the top of the page. This will take you to a page where you can choose the parameters for
the over-representation analysis.
First you need to specify whether you are analyzing an entire array dataset or just a subset of genes. If you try to analyze a subset of genes using the entire dataset algorithm or vice versa your results will NOT be correct.
A new page will be returned showing the GO terms that are significantly associated with up-regulated genes.
Click the green button to see the GO terms that are significantly associated with down-regulated genes.
Click on the 'summary' link to see information for a specific GO term.
