SYNOPSIS

splazers [OPTIONS] <GENOME FILE> <READS FILE> splazers [OPTIONS] <GENOME FILE> <READS FILE 1> <READS FILE 2>

DESCRIPTION

SplazerS uses a prefix-suffix mapping strategy to split-map read sequences.If a SAM file of mapped reads is given as input, all unmapped but anchoredreads are split-mapped onto anchoring target regions (specify option -an),if a Fasta/q file of reads is given, reads are split-mapped onto the wholereference sequence.

REQUIRED ARGUMENTS

ARGUMENT 0 INPUT_FILE

A reference genome file. Valid filetypes are: .sam, .raw, .gbk, .frn, .fq, .fna, .ffn, .fastq, .fasta, .faa, .fa, .embl, and .bam.

READS List of INPUT_FILE's

Either one (single-end) or two (paired-end) read files. Valid filetypes are: .sam, .raw, .gbk, .frn, .fq, .fna, .ffn, .fastq, .fasta, .faa, .fa, .embl, and .bam.

OPTIONS

-h, --help

-le, --library-error INTEGER

Paired-end library length tolerance. In range [0..inf]. Default: 50.

-m, --max-hits INTEGER

Output only <NUM> of the best hits. In range [1..inf]. Default: 100.

--unique

Output only unique best matches (-m 1 -dr 0 -pa).

-tr, --trim-reads INTEGER

Trim reads to given length. Default: off. In range [14..inf].

-a, --alignment

dump the alignment for each match

-pa, --purge-ambiguous

purge reads with more than max-hits best matches

-dr, --distance-range INTEGER

only consider matches with at most NUM more errors compared to the best (default output all)

-of, --output-format INTEGER

Set output format. 0 = RazerS, 1 = Enhanced Fasta, 2 = Eland, 3 = GFF, 4 = SAM. In range [0..4].

-gn, --genome-naming INTEGER

Select how genomes are named. 0 = use Fasta id, 1 = enumerate beginning with 1. In range [0..1]. Default: 0.

-rn, --read-naming INTEGER

Select how reads are named. 0 = use Fasta id, 1 = enumerate beginning with 1. In range [0..1]. Default: 0.

-so, --sort-order INTEGER

Select how matches are sorted. 0 = read number, 1 = genome position. In range [0..1]. Default: 0.

-pf, --position-format INTEGER

Select begin/end position numbering (see Coordinate section below). 0 = gap space, 1 = position space. In range [0..1]. Default: 0.

Split Mapping Options::

-sm, --split-mapping INTEGER

min. match length for prefix/suffix mapping (to disable split mapping, set to 0) Default: 18.

-maxG, --max-gap INTEGER

max. length of middle gap Default: 10000.

-minG, --min-gap INTEGER

min. length of middle gap (for edit distance mapping about 10% of read length is recommended) Default: 0.

-ep, --errors-prefix INTEGER

max. number of errors in prefix match Default: 1.

-es, --errors-suffix INTEGER

max. number of errors in suffix match Default: 1.

-gl, --genome-len INTEGER

genome length in Mb, for computation of expected number of random matches In range [-inf..10000]. Default: 3000.

-an, --anchored

anchored split mapping, only unmapped reads with mapped mates will be considered, requires the reads to be given in SAM format

-pc, --penalty-c INTEGER

percent of read length, used as penalty for split-gap Default: 2.

Filtration Options::

-oc, --overabundance-cut INTEGER

Verification Options:

-mN, --match-N
