**What it does**

SortMeRNA_ is a software designed to rapidly filter ribosomal RNA fragments
from metatransriptomic data produced by next-generation sequencers.
It is capable of handling large RNA databases and sorting out all fragments
matching to the database with high accuracy and specificity.

.. _SortMeRNA: http://bioinfo.lifl.fr/RNA/sortmerna/


**Input**

The input is one file of reads in FASTA or FASTQ format and any number of rRNA databases to search against.
If the user has two foward-reverse paired-sequencing reads files, they may use
the script "merge_paired_reads.sh" to interleave the reads into one file, preserving their order.

If the sequencing type for the reads is paired-ended, the user has two options under
"Sequencing type" to filter the reads and preserve their order in the file.
For a further example of each option, please refer to Section 4.2.3 in the `SortMeRNA User Manual`_.

.. _sortmerna user manual: http://bioinfo.lifl.fr/RNA/sortmerna/code/SortMeRNA-user-manual-v1.7.pdf


**Output**

The output will follow the same format (FASTA or FASTQ) as the reads. Optionally, a statistic file for the rRNA content of reads, as well as rRNA subunit distribution can be generated.


**rRNA databases**

SortMeRNA is distributed with 8 representative rRNA databases, which were
all constructed from the SILVA SSU,LSU (version 111) and the RFAM 5/5.8S
(version 11.0) databases using the tool UCLUST.

id %: members of the cluster must have identity at least 'id %' identity with the representative sequence

average id %: average identity of a cluster member to the representative sequence

The user may also choose to use their own rRNA databases.

Note that your personal databases are indexed each time. The public ribosomal
databases are indexed when added, but they can be re-indexed with non-default indexing 
parameters. The indexing may take some time depending on the size of the given database.
