FatiGO

FatiGO is a web interface which carries out datamining using Gene Ontology for DNA microarray data. The datamining consists on the assignation of the most characteristic Gene Ontology term to each cluster. GO terms are related to Human, Mouse, Rat, Arabidopsis, Fly, Worm and Yeast genes and proteins.

FatiGO implements Fisher's exact test for 2x2 contingency tables for comparing two groups of genes and extracting a list of GO terms distribution among the groups is significantly different.The results of the test are corrected for multiple-testing to obtain an adjusted-pvalue. The results are displayed in HTML and txt format and also we represent a tree view with GO terms associated with the list of genes and the number of genes annotated to a specific GO term.
