A mothur names file specifies the result of
clustering sequences into OTUs. It contains exactly the same information as one row in a
mothur list file. The format is tabbed
text. Each line represents one cluster. A line has two fields:
1.
Sequence label. Presumably, this is the OTU
representative sequence. 2. Comma-separated
list of cluster member
sequence labels. The first label is the representative sequence (same as
field 1).
