[Bioperl-l] Problem with accession number in Genbank

[William Boileau]

  Hello,

 I'm trying to get transcript informations using Refseq accession numbers,
 but with XM_ numbers, I only have information in fasta format, instead of
  genbank format, but I can't get annotation references in this format. Is
 there a way to get these references with XM_ numbers ?
Thank you for any answer !
