[Biopython-dev] FormatIO and SwissProt

[Yves Bastide]

Hi,

FormatIO doesn't seem to handle SwissProt files well...

bionix:~/src/bio/biopython/Tests% python
Python 2.2.2 (#1, Feb 14 2003, 12:23:31)

>>> from Bio import SeqRecord
>>> sequence_iterator = SeqRecord.io.readFile(open("SwissProt/sp008"))
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "/.amd/archipel/export/archive/d08/symbiose/ybastide/src/bio/biopython/build/lib.linux-i686-2.2/Bio/FormatIO.py", line 97, in readFile
     raise TypeError("Could not determine file type")
TypeError: Could not determine file type

[OK, there are two Swissprot parsers.  Erm, why */build/lib-*/Bio/FormatIO.py?
It's certainly not in my path :)]

 >>> sequence_iterator = SeqRecord.io.readFile(open("SwissProt/sp008"), format="swissprot/40")
 >>> sequence_iterator.next()
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
