# fasta2frag(1)

splits a single fasta sequence into several overlapping fragments.

## NAME

**fasta2frag - splits a single fasta sequence into several overlapping fragments.**

## DESCRIPTION

This program is part of the MIRA assembler package.  The purpose of fasta2frag is to fragment sequences into smaller, overlapping subsequences. It can be used for simulating shotgun sequences. It can create subsequences in both directions (/default) and also paired-end sequences. Please check out the documentation below for more detailed information about fasta2frag.

## SYNOPSIS

fasta2frag *\<options\> infile outfile*

## OPTIONS

**-l** int      Length of fragments (default=3000)

- **-i**

  int      Increment of fragment start site (default=2500)

- **-p**

  int      Paired end (default=0 is off, 1 is on)

- **-P**

  int      In paired-end mode, reverse one of the reads (0 is off, default=1 is on)

- **-s**

  int      Strobe sequencing (default=0 is off, 1 is on)

- **-q**

  int      Default quality when no quality data present (default=30)

- **-r**

  int      Reverse every nth fragment (default=2)

- **-c**

  int      Circularise fragments so that they form a ring

-

  (default=0 is is off, 1 would be on)

- **-qualdivisor**

  int      Divide quality values by this (default=1)

- **-minqual**

  int      But give it at least this qual (default=0)

- **-insert\_size**

  int      paired-end: insert size (default=3000)

- **-insert\_stdev** int

  paired-end: standard dev (default=900) this is not working at the moment

- **-pairednaming** string

  naming scheme for paired-end: sanger, 454 (default) or solexa

- **-minmut**

  int      min. number of mutations/seq. errors (def=0)

- **-maxmut**

  int      max. number of mutations/seq. errors (def=0)

- **-strobeon**

  int      number of bases read during strobe on

- **-strobeoff**

  int      number of bases during strobe off

- **-startoffset**

  int      start at offset position

- **-namesuffix**

  string   suffix name with string
