GO annotation

[Ramet]

Hi all!

I have a problem with GO annotation of my BLAST results. So far I used Blast2GO, but for several reasons I am a bit unsatisfied with the programme.
In addition I need a good export function because I want to further analyse the data in MS Excel.

Can anyone name a sufficient programme which
- annotates GO terms for .xml files or swissprot accesion IDs (BLAST mustn't be done there!)
- possibility to only export level 2 GO terms
- possibility to export GO terms in tab-delimited form or equal for further analysis in Excel (information about category MF, BP, CC should be maintained!)

Thanks to everyone in advance!
