parsing BioGrid data

[fee]

Hi all, wondering if someone could help.

I wanted to download the non-redundant human protein protein
interaction network from BioGrid. But I think I've to download the raw
interactions and parse it myself (in python). Would the best way to go
about this be to:

1. remove all the rows in the interaction file which are not physical
interactions (i,e they are genetic)
2. remove the rows which has the same 2 proteins (ie if row 1 connects
protein A and B, and row 2 connects A and B, remove row 2)
3. maybe something to do with organisms, to make sure I'm only looking
at human-human interactions?

Thanks for any help
:)
