Prediction of GO terms

GOPET

http://genius.embnet.dkfz-heidelberg.de/menu/biounit/open-husar

We used the default settings (GO aspect: molecular function, maximum number of predictions: 20, confidence threshold: 60, GOPET model 2007 june, version 2.0, GOPET database 2007). The results only contain GOids of the GO aspect "molecular function", since the other two GO aspects (cellular component and biological process) were not available.
