MiDAS taxonomy (version 2.1) is a manually curated SILVA 16S rRNA taxonomy (release 1.23 Ref NR99) that proposes a name for all the abundant genus-level taxa present in activated sludge, anaerobic digesters and influent wastewater (based on MiDAS survey of 24 Danish wastewater treatment plants, click here for details).
The MiDAS taxonomy has been pre-formatted for the QIIME pipeline.
1) Download the QIIME preformatted taxonomy files here:
midas_s123_213tar.gz (143 MB)
2) Unpack the downloaded file using e.g. the command line (unix):
tar xzvf MiDAS_S123_2.1.3.tar.gz
3) Use the unpacked files directly in the QIIME pipeline (see here):
assign_taxonomy.py -i my_otus.fasta -r MiDAS_S123_2.1.3.fasta -t MiDAS_S123_2.1.3.tax
Previous MiDAS taxonomy version: 1.20.
Changes introduced in MiDAS version 2.1: additional curation of genus-level classification of all the taxa abundant in anaerobic digesters and influent wastewater.
