[BioPython] Blast descriptions and alignments

[Atkinson, GC]

Hi,

I'm doing a qblast and I'm having problems retrieving 500 alignments and 
descriptions.

I'm using:

b_results=NCBIWWW.qblast('blastp','nr',record, descriptions = 500, 
alignments = 500)

It just retrieves about 100 results, though doing a blast search without 
my Python script gets the full 500.

Any ideas?
