Fwd: Generic GO Slims file is missing GOids compared to most recent fasta flat file

Hi - can anyone help Jessica? She wants to find the GO slim  
categories for a large (22,000) set of GO ids (not in gene  
association file format, so she can't use map2slim). Does anyone know  
of/develop any software that can do this?
