[Bioperl-l] invalid species name error handling

[Stefano Ghignone]

Hi all.
I have a problem with a script that extracts the species name from GenPept flat files, querying the database with a list of acc.no. When it encounters an invalid species name (e.g. Cryptococcus neoformans var. neoformans JEC21), it exits definitely with an exception error. I don't know how to handle this error, and make the script pass to the next value. I suppose I have to use Bio::Root::Exception and Bio::Root::Root but I don't know how to start.
Who can help me with some hints?
