beta diversity: how to select metrics

[diana123 (roy d)]

Can anyone help me with this query

So to run the ace / chao1 we have to write the command like this

qiime diversity beta
--i-table table.qza
--p-metric ace
--o-distance-matrix ace_result.qza

Or like this

qiime diversity beta
--i-table table.qza
--p-metric:ace
--o-distance-matrix ace_result.qza

Hello @diana123 !
I am waiting for an answer, so maybe I can help you in the meanwhile.
I found the guidelines here: beta: Beta diversity — QIIME 2 2023.2.0 documentation

I don't think you should use the columns between --p-metric and ace, so I think the first option is the correct one. It is in fact quite unusual in Qiime that you use signs after the feature of the command you are giving to express your preference.

Hope this is helpful, have a nice day!
