.SH NAME
razers \- Fast Read Mapping with Sensitivity Control
.PP
SYNOPSIS
.IP
razers [OPTIONS] <GENOME FILE> <READS FILE>
razers [OPTIONS] <GENOME FILE> <MP\-READS FILE1> <MP\-READS FILE2>
.PP
DESCRIPTION
.IP
RazerS is a versatile full\-sensitive read mapper based on a k\-mer counting
filter. It supports single and paired\-end mapping, and optimally
parametrizes the filter based on a user\-defined minimal sensitivity. See
http://www.seqan.de/projects/razers for more information.
.IP
Input to RazerS is a reference genome file and either one file with
single\-end reads or two files containing left or right mates of paired\-end
reads. Use \- to read single\-end reads from stdin.

FORMATS, NAMING, SORTING, AND COORDINATE SCHEMES
.IP
RazerS supports various output formats. The output format is detected
automatically from the file name suffix.
.IP
\&.razers
.IP
Razer format
.IP
\&.fa, .fasta
.IP
Enhanced Fasta format
.IP
\&.eland
.IP
Eland format
.TP
\&.gff
GFF format
.IP
By default, reads and contigs are referred by their Fasta ids given in the
input files. With the \fB\-gn\fR and \fB\-rn\fR options this behaviour can be changed:
.TP
0
Use Fasta id.
.TP
1
Enumerate beginning with 1.
.TP
2
Use the read sequence (only for short reads!).
.IP
The way matches are sorted in the output file can be changed with the \fB\-so\fR
option for the following formats: razer, fasta, sam, and amos. Primary and
secondary sort keys are:
.TP
0
1. read number, 2. genome position
.TP
1
1. genome position, 2. read number
.IP
The coordinate space used for begin and end positions can be changed with
the \fB\-pf\fR option for the razer and fasta formats:
.TP
0
Gap space. Gaps between characters are counted from 0.
.TP
1
Position space. Characters are counted from 1.

.IP
Map single\-end reads with 4% error rate, indels, and output the

.IP
razers example/genome.fa example/reads.fa example/reads2.fa \fB\-id\fR \fB\-mN\fR
.IP
Map paired\-end reads with up to 4% errors, indels, and output
concordantly mapped pairs within default library size. Ns are
considered to match everything.
