[Bioperl-l] can't locate object method "next_result" (probably a simple problem)

[Brian Osborne]

Andy,

Change "btblastall" to "blastall", let's see what happens.

A question: does your search work from the commandline?

>blastall -p blastx -d Tetraodon_nigroviridis.TETRAODON7.mar.pep.fa -i
blast_input.fasta

Something like that...
