pdb_seq.py does not deal gracefully with multiple MODEL pdb files when in --atomseq mode

[GoogleCodeExporter]

What steps will reproduce the problem?

Assume "my_nmr_struct.pdb" contains the coordinates for multiple MODELs
(eg, typical for NMR structures).

1. Run $ pdb_seq.py -a my_nmr_struct.pdb 

What is the expected output? What do you see instead?

I expect to see:
>my_nmr_structA_1
ASDFGHASDGSDFHG

... the FASTA format output for the first model. Typically all model
sequences are identical, so we don't care about every model sequence.

Currently, pdb_seq.py -a outputs the sequence of all models concatenated, like.
>my_nmr_structA_1
ASDFGHASDGSDFHGASDFGHASDGSDFHG
ASDFGHASDGSDFHGASDFGHASDGSDFHG
ASDFGHASDGSDFHGASDFGHASDGSDFHG
ASDFGHASDGSDFHGASDFGHASDGSDFHG
...etc, as if all models are one long chain.

Alternatively, "pdb_seq.py -a" could output FASTA sequences for all models.
eg:
$ pdb_seq.py -a my_nmr_struct.py
>my_nmr_structA_1
ASDFGHASDGSDFHG
>my_nmr_structA_2
ASDFGHASDGSDFHG
>my_nmr_structA_3
ASDFGHASDGSDFHG
.....
>my_nmr_structA_20
ASDFGHASDGSDFHG

eg ... one FASTA sequence per model in the file.
