NAME
gustaf - Gustaf - Generic mUlti-SpliT Alignment Finder: Tool for split-read mapping
allowing multiple splits.
SYNOPSIS
gustaf [OPTIONS] <GENOME FASTA FILE> <READ FASTA FILE>
DESCRIPTION
GUSTAF uses SeqAns STELLAR to find splits as local matches on different strands or
chromosomes. Criteria and penalties to chain these matches can be specified. Output
file contains the breakpoints along the best chain.
The genome file is used as database input, the read file as query input.
All STELLAR options are supported. See STELLAR documentation for STELLAR parameters
and options.
