[Bioperl-l] Running into problems

I'd probably cheat a bit and optimise my blast parameters so there's less output to process.
Also, are you sure an e-value of 100 is what you're after? I'd be aiming much lower - probably 1e-6.
It also pays to mask repeats if you're blasting against a whole genome to cut down on the number of rubbish hits.
