[Bioperl-l] Problems with DB::GenBANK and species()->common_name()

[Stephen Montgomery]

Hi-
I'm using Bio::DB::GenBank to get_Seq_by_id() where id is the accession 
id.  I then want to report species info and seq info to STDOUT. 
 However, I get an intermittent error...
my program will report a

Can't call method "species" on an undefined value at ...

I checked that the accession entries I'm using always have a species in 
GenBank.  The troubling thing is sometimes the script runs 10 accession 
numbers sometimes 1.  So it is moreorless randomly reporting this error. 
 (These are always the same accession numbers in my test)

Thanks for any help.
Cheers,
Stephen
