SortMeRNA is a local sequence alignment tool for filtering, mapping and clustering.
The core algorithm is based on approximate seeds and allows for sensitive analysis of NGS reads. The main application of SortMeRNA is filtering rRNA from metatranscriptomic data. SortMeRNA takes as input files of reads (fasta, fastq, fasta.gz, fastq.gz) and one or multiple rRNA database file(s), and sorts apart aligned and rejected reads into two files. SortMeRNA works with Illumina, Ion Torrent and PacBio data, and can produce SAM and BLAST-like alignments.
SortMeRNA is also available through QIIME v1.9.1 and the nf-core RNA-Seq pipeline v.3.9.
SortMeRNA 4 is C++17 compliant, and mostly uses standard libraries. It uses CMake as the build system, and can be run/built on all major OS including Linux, Windows, and Mac.

- The only required options are
--ref
and--reads
- Options (any) can be specified usig a single dash e.g.
-ref
and-reads
- Both plain
fasta/fastq
and archivedfasta.gz/fastq.gz
files are accepted - file extensions
.fastq, .fastq.gz, .fq, .fq.gz, .fasta, ...
are optional. The format and compression are automatically recognized - Relative paths are accepted
for example
# single reference and single reads file
sortmerna --ref REF_PATH --reads READS_PATH
# for multiple references use multiple '--ref'
sortmerna --ref REF_PATH_1 --ref REF_PATH_2 --ref REF_PATH_3 --reads READS_PATH
# for paired reads use '--reads' twice
sortmerna --ref REF_PATH_1 --ref REF_PATH_2 --ref REF_PATH_3 --reads READS_PATH_1 --reads READS_PATH_2
