Hello!
In Aldex2 in qiime2 only two groups may be compared at the same time.
The workaround will be to compare all your groups one versus another, export differentials.qza file (which contains all p-values, significant and non-significant in one file), pool tables together from each comparison in one and readjust p-values for multiple testing.
