list file
The file ending in “list” contains data indicating the sequences that cluster together within an OTU. Like the rabund and sabund files, the first column represents the distance that sequences were assigned to OTUs. If you are making your own rabund file you can make the label anything without spaces. The number in the second column is the number of OTUs that have been formed. Subsequent columns contain the names of sequences within each OTU separated by a comma. At this time these are not sorted according to any rule.
