 Fasta files are processed using [[http://​qiime.org|QIIME'​s]] pick_open_reference_otus.py workflow with default parameters (97% similarity) and taxonomy assignment and alignment features suppressed. The resulting OTU table is filtered to remove any OTU with an abundance of less than 0.05%. Representative OTU sequences are then BLASTed against the reference database ([[http://​greengenes.lbl.gov/​cgi-bin/​nph-index.cgi|Greengenes]] version 2013/05 for 16S, [[http://​www.arb-silva.de|Silva]] version 119 for LSU, and [[http://​unite.ut.ee|UNITE]] singleton included release 04/07/2014 for fungal ITS amplicons). The main analysis output is an OTU table comprising the taxonomic classification of the best database match and a representative sequence for each OTU. Fasta files are processed using [[http://​qiime.org|QIIME'​s]] pick_open_reference_otus.py workflow with default parameters (97% similarity) and taxonomy assignment and alignment features suppressed.
