I am working on a research project where I need to add Gene Ontology terms for each hits from NCBI BLAST result. How can I look up GO terms for each hits using BioMart? Possible input values that I can use for the GO term lookup are Accession ID, GI ID, and Taxon ID.
I've been attempting to obtain GO terms by manually searching through downloaded databases with no luck. I tried Blast2GO, but it just doesn't work anymore and I can't afford to purchase Blast2GO pro. I'm still very new to the field of bioinformatics. How do people in the field of bioinformatics go about looking up GO terms in general?
Your help will be very appreciated.
