.SH NAME
.LP
\fBsplit_fasta\fP - Split a fasta file according to sequence and character counts

.SH SYNOPSIS
.LP
\FC\fBsplit_fasta query_granularity character_granularity fasta_file\fP\FT

.SH DESCRIPTION
.LP
\fBsplit_fasta\fP 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.

.SH OPTIONS
.LP

.SH EXIT STATUS
.LP
On success, returns zero.  On failure, returns non-zero.

.SH ENVIRONMENT VARIABLES

.SH EXAMPLES
.LP

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:
.fam C
.nf
.nh
.IP "" 8
python split_fasta 500 10000 smallpks.fa
.fi
.hy
.fam
.P
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.
