Beta diversity metadata

I have started the QIIME 2 analysis with two samples.I am getting the following error when I gave the command for beta group significance-
All values in the grouping vector are the same. This method cannot operate on a grouping vector with only a single group of objects (e.g., there are no ‘between’ distances because there is only a single group).
Am I getting this error because I just have two samples?
It would be great if I get a guidance soon.

Hey @kkcool,

Almost, it’s saying that the metadata column you gave it has the same value for both samples, so there’s no second group for it to compare against since both samples end up in the same group.

Would you be able to provide the command you ran and your metadata (if possible)? That will let me confirm the above.

Hope that helps!
