Razers

Generic Workflow Nodes for KNIME: SeqAn version 2.3.2.201707261654 by Freie Universitaet Berlin, Universitaet Tuebingen, and the SeqAn Team

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.

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.

Options

version-check
Turn this option off to disable version update notifications of the application.
forward
Map reads only to forward strands.
reverse
Map reads only to reverse strands.
percent-identity
Percent identity threshold.
recognition-rate
Percent recognition rate.
param-dir
Read user-computed parameter files in the directory <DIR>.
indels
Allow indels. Default: mismatches only.
library-length
Paired-end library length.
library-error
Paired-end library length tolerance.
max-hits
Output only <NUM> of the best hits.
unique
Output only unique best matches (-m 1 -dr 0 -pa).
trim-reads
Trim reads to given length. Default: off.
verbose
Verbose mode.
vverbose
Very verbose mode.
alignment
Dump the alignment for each match (only razer or fasta format).
purge-ambiguous
Purge reads with more than <max-hits> best matches.
distance-range
Only consider matches with at most NUM more errors compared to the best. Default: output all.
genome-naming
Select how genomes are named (see Naming section below).
read-naming
Select how reads are named (see Naming section below).
sort-order
Select how matches are sorted (see Sorting section below).
position-format
Select begin/end position numbering (see Coordinate section below).
shape
Manually set k-mer shape.
threshold
Manually set minimum k-mer count threshold.
overabundance-cut
Set k-mer overabundance cut ratio.
repeat-length
Skip simple-repeats of length <NUM>.
taboo-length
Set taboo length.
low-memory
Decrease memory usage at the expense of runtime.
match-N
N matches all other characters. Default: N matches nothing.
error-distr
Write error distribution to FILE.
min-clipped-len
Set minimal read length for read clipping.
quality-in-header
Quality string in fasta header.

Views

Razers Std Output
The text sent to standard out during the execution of Razers.
Razers Error Output
The text sent to standard error during the execution of Razers. (If it appears in gray, it's the output of a previously failing run which is preserved for your trouble shooting.)
