Fig. 2From: GeFaST: An improved method for OTU assignment by generalising Swarm’s fastidious clustering approachWorkflow of GeFaST. The amplicons from one or more input files are preprocessed and grouped into pools. Within each pool, OTUs are formed by finding similar sequences using a segment filter. Optionally (denoted by dashed frames), OTUs can be refined by fastidious clustering. Finally, the different kinds of output are generated from the OTUs of all amplicon poolsBack to article page
