Making an OTU table (otutab command)

Combines counts from sets of samples (groups). The input file must be in QIIME classic format .

Groups are specified in a group file, which is a tabbed text file given by the -labels option. Each line in the group file must have two fields: the sample identifier and the group identifier. Some samples may be omitted, and a sample may appear in more than one group. For example, the following group file specifies two groups, mock and soil , each with three samples.

Mock1    mock
Mock2    mock
Mock3    mock
Soil1    soil
Soil2    soil
Soil3    soil

The output file is specified by the -output option. The output file is also in QIIME classic format.

Example

usearch -otutab_group otutable.txt -labels groups.txt -output otutable_groups.txt
