[Bioperl-l] Error while running load_seqdatabase.pl

That's odd indeed. Did you try and put a print statement before the  
return statement that proves that 1) the codes gets executed, and 2)  
display_id(), primary_id() and accession_number() have the expected  
values?

BTW you might also want to set primary_id() to undef (as the ID found  
in the FASTA files doesn't really count as a primary database- 
specific ID anyway). The identifier column in bioentry (which  
primary_id() maps to) is constrained to 40 chars as well.
