micca - MICrobial Community Analysis


micca (MICrobial Community Analysis) is a software pipeline for the processing of amplicon sequencing data, from raw sequences to OTU tables, taxonomy classification and phylogenetic tree inference. The pipeline can be applied to a range of highly conserved genes/spacers, such as 16S rRNA gene, Internal Transcribed Spacer (ITS) and 28S rRNA.

Key features

  • supports single-end (Roche 454, Illumina MiSeq/HiSeq ,Ion Torren) as well overlapping paired-end reads (Illumina MiSeq/HiSeq);
  • multithread de novo greedy clustering as well closed-reference and open-reference OTU picking protocols are available;
  • state-of-the-art taxonomic classification algorithms are available (RDP and consensus-based classifier);
  • fast (multithread) and and memory efficient implementation of the NAST multiple sequence alignment (MSA);
  • filter low quality sequences according to the maximum allowed expected error (EE) rate %;
  • simple, easy to use.
