Hi all,

I have a set a bacterial genome (fasta format) and a multifasta file with all the predicted proteins from the same genome, translated using bioperl.

In order to use a particular software to analyze these sequences, I need to have a genbank format file of the genome, shaped as:

Is there any intelligent and quick way to do this using external software / Python / R? I reckon I can go on and manually parse the file but I don't think it is the smartest way to proceed...

Ah, and I don't want to submit the sequences to NCBI so I think I can't use the software they provide for their submissions, as it seems to be that it requires to submit the file. Thanks a lot!
