           Summary: If a SeqRecord containing Genbank information is read
                    from BioSQL, it cannot be written to another BioSQL
                    database
           Product: Biopython
           Version: 1.49
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: BioSQL
        AssignedTo: biopython-dev at biopython.org
        ReportedBy: david.wyllie at ndm.ox.ac.uk


I've been trying to annotate some microbial sequences; some are from genbank.
So the proposed series of events was:
1) get sequences from genbank
2) store in BioSQL database called One
3) recover them from BioSql
4) annotate the recovered SeqRecords [this works, but isn't necessary for this
problem to be reproduced - here, I'm making no changes at all to the SeqRecord]
5) store the annotated SeqRecords in a different BioSQL database called Two.

The problem is that Step 5 fails when the original record was recovered from
Genbank.

The traceback (below) indicates a problem with the BioSQL loader in 
_load_bioentry_date

Here is the screen output, including traceback.
The program (attached) first loads a record from Genbank,
writes it to One, recovers it from One; at this point it has changed, in
particular in the way date fields are represented.

 the entrez load has a /date feature which is not a list
 /date=26-MAY-2005
 while the reloaded version has two date fields
 /dates=['26-MAY-2005']
 /date=['26-MAY-2005']  

Whether this is relevant I'm not sure. 

The subsequent write of the recovered version to Two fails.
As a control, I've checked that the original version can be written to Two
successfully.

I'm a novice with Python and Biopython so please accept my apologies if there
is something obvious and very stupid responsible for this.
