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 count.seqs command counts the number of sequences represented by the representative sequence in a name file and generates a count_table. If a group file is given, it will also provide the group count breakdown.
