NAME

       split_fasta - Split a fasta file according to sequence and character counts

SYNOPSIS

       split_fasta query_granularity character_granularity fasta_file

DESCRIPTION

       split_fasta  is  a  simple  script  to  split  a  fasta  file  according  to user provided
       parameters.  The script iterates over the given file, generating  a  new  sub_file  called
       input.i  each  time  the  contents of the previous file (input.(i-1)) exceed the number of
       queries  given   by   query_granularity   or   the   number   of   characters   given   by
       character_granularity.

OPTIONS

EXIT STATUS

       On success, returns zero.  On failure, returns non-zero.

ENVIRONMENT VARIABLES

EXAMPLES

       To split a fasta file smallpks.fa into pieces no larger than 500 queries and with no piece
       receiving additional sequences if it exceeds 10000 characters we would do:

               python split_fasta 500 10000 smallpks.fa

       This would generate files input.0,  input.1,  ...,  input.N  where  N  is  the  number  of
       appropriately constrained files necessary to contain all sequences in smallpks.fa.
