[Bioperl-l] How to get Remote BLAST results in a single out

Thank you very much for your answers, but due to them, I'm afraid I didn't
explained myself good enough.

 I'm not looking for another tool to perform a BLAST task. I was just
wondering if there was a way to simply change the way the module writes the
outputs, so that I can get multiple searches in a single report file
instead of having a report for each BLAST search.

Maybe there's some issue I ignore, that makes you recommend the use of
other tools instead of the Bioperl Remote BLAST module...it would be
appreciated if you let me know about that (NCBI server problems with
web-services or so)...

Thank you for your answers anyway

Best wishes
