Mothur is a comprehensive suite of tools for microbial ecology community. It is initiated by Dr. Patrick Schloss and his software development team in the Department of Microbiology and Immunology at The University of Michigan. For more information, see Mothur-Wiki.
The get.coremicrobiome command determines the fraction of OTUs that are found in varying numbers of samples for different minimum relative abundances.
