how to convert feature ID to OTU?

[colinbrislawn (Colin J Brislawn)]

You can rename features using the feature-table plugin:

But... this may be a bad idea!

You can technically do this with the feature-table rename-ids function (see here ) but personally I wouldn't recommend it. Changing the feature-ids in your feature table will break the link between the id and say your phylogenetic tree, taxonomy, and rep-seqs artifacts, which you may need for downstream analysis. What I generally do is get my data to the final stages and for plotting purposes I change the names on the fly in R.

If you can give us a more specific example of what you want to do and with what platform we may be able to help you get there more efficiently.
