The mailing list doesn't like attachments, but I got them and
had a look. This is odd. I just tied a conversion using 1.52+
(i.e. the latest code in the repository) with:
from Bio import SeqIO
count = SeqIO.convert("original.txt", "gb", "new.txt", "gb")
print "Converted %i records" % count
or, equivalently for pre-Biopython 1.52 you can use:
from Bio import SeqIO
records = SeqIO.parse(open("original.txt"), "gb")
handle = open("new.txt", "w")
count = SeqIO.write(records, handle, "gb")
handle.close()
print "Converted %i records" % count
See this blog post introducing the convert function:
http://news.open-bio.org/news/2009/09/biopython-convert-function/
Either way, I am seeing the features preserved (although
some of the qualifiers are in a different order). As I said
before, I thought this would work on 1.51 too - but maybe
I was wrong. Could you upgrade to 1.52 and retry?
