Hi biohisham and thanks for the replay

Also sorry for the lateness of my replay! I was away from the internets during the holidays.

I have looked at the $fac->cleanup and it did not work. But now i think that i need to take a look at my factory and how i create the database.

Thank you very much for the info and the unlink i will take a look into that also.

I look forward to read up on Perl and Bioinformatics. And if it is all right i might even be so bald and send you a PM with a question or two about bioperl if i get really stuck.

Best regards Róbert
