I always come back to BioStar because the help is always useful and quick and the people are always so considerate. I'm sure this experience will be no different.
I am performing an analysis on someone's custom Agilent array design. I am trying to map each /many of the genes on the chip to a GO term (if such an annotation exists). This would be simple if all of the IDs were from one source (ENSEMBL, Genbank, etc). Instead, what I have is a mix of different identifier types for the chip.
I have gone to BioMart and - while hugely powerful - it seems to require that all of the IDs come from the same source. I can separate these out, but I'm wondering if there is a site that can recognize the type of identifier you have and then bring GO terms for you.
I do not have the files used to generate the arrays. I do, however, have the ProbeIDs, SystematicIDs, etc. from the array intensity files.
Thanks in advance for any help you can offer!
