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.
