This is a two-column, TAB-delimited file that describes which samples belong to which groups. It is a required input for computing enrichment scores of metabolic modules in anvi-compute-functional-enrichment.

Here is an example:

sample group
sample_01 GROUP-A
sample_02 GROUP-B
sample_03 GROUP-A
(…) (…)

The names in the sample column must match those in the “modules” mode output file that you provide to the anvi-compute-functional-enrichment program. If you know that the sample names match but you are still getting errors, you might need to specify which column in the “modules” mode output contains those sample names using the --sample-header parameter of anvi-compute-functional-enrichment.
