Command Documentation
The classify.otu command assigns sequences to chosen taxonomy outline.
The basis parameter allows you indicate what you want the summary file to represent, options are otu and sequence. Default is otu. For example consider the following basis=sequence could give Clostridiales 3 105 16 43 46, where 105 is the total number of sequences whose otu classified to Clostridiales. 16 is the number of sequences in the otus from groupA, 43 is the number of sequences in the otus from groupB, and 46 is the number of sequences in the otus from groupC. Now for basis=otu could give Clostridiales 3 7 6 1 2, where 7 is the number of otus that classified to Clostridiales. 6 is the number of otus containing sequences from groupA, 1 is the number of otus containing sequences from groupB, and 2 is the number of otus containing sequences from groupC.
v1.21.0: Updated to use Mothur 1.33. Added count parameter (1.28.0) and persample parameter (1.29.0)
