[BioPython] Genbank parsing problem and fix

[gca500 at york.ac.uk]

Hi All,

Been having a problem using the Genbank RecordParser with some Genbank 
files that have recently been added to NCBI. After a bit of trial and 
error, I realised the problem only occurs if a REFERENCE field isn't 
followed by an AUTHOR field (for example in reference 2 of this record: 
http://www.ncbi.nlm.nih.gov/entrez/viewer.fcgi?db=protein&val=88602864).

There's a very easy fix on line 289 of Genbank.py. Decided to post this to 
the list to save any one else who stumbles across this problem tearing 
their hair out like I've been doing this afternoon!

Change:

authors_block + 

to: 

Martel.Opt(authors_block) +

and it works! 

Hope this is useful,

Gemma
