This script requires at least 52GB RAM.
It is designed for NERSC and uses hard-coded paths.
Description: Removes all reads that map to the cat, dog, mouse, or human genome with at least 95% identity after quality trimming.
Removes approximately 98.6% of human 2x150bp reads, with zero false-positives to non-animals.
NOTE! This program uses hard-coded paths and will only run on Nersc systems.
Usage: removecatdogmousehuman.sh in=<input file> outu=<clean output file>
Input may be fasta or fastq, compressed or uncompressed.
Parameters:
threads=auto (t) Set number of threads to use; default is number of logical processors.
overwrite=t (ow) Set to false to force the program to abort rather than overwrite an existing file.
interleaved=auto (int) If true, forces fastq input to be paired and interleaved.
trim=t Trim read ends to remove bases with quality below minq.
Values: t (trim both ends), f (neither end), r (right end only), l (left end only).
untrim=t Undo the trimming after mapping.
minq=4 Trim quality threshold.
ziplevel=2 (zl) Set to 1 (lowest) through 9 (max) to change compression level; lower compression is faster.
outm=<file> File to output the reads that mapped to human.
***** All BBMap parameters can be used; run bbmap.sh for more details. *****
Please contact Brian Bushnell at bbushnell@lbl.gov if you encounter any problems.
