[Bioperl-l] beginner problem with fasta headers

[Carlos Villacorta]

hi all,
I have a embl sequence file, when formatting to fasta with Seqio it
gives a long string header for each sequence that my following
phylogenetic software cannot handle...
Does anyone knows how to format those embl or genbank files to fasta
but retrieving in the headers just two or three fields (e.g. id | gene
| sp_name)?
Any advice with this problem would be very appreciated, thanks!
