Hello Colin,

Thank you for this explanation again!  
However, I am still a bit confused in the order. Please let me know if I have interpreted this the correct way or not:

When looking at the PD mouse tutorial adonis:

qiime diversity adonis   
--i-distance-matrix core-metrics-results/unweighted\_unifrac\_distance\_matrix.qza   
--m-metadata-file metadata.tsv   
--o-visualization core-metrics-results/unweighted\_adonis.qzv   
--p-formula genotype+donor

By putting genotype first in the formula (genotype + donor, not donor+genotype) I adjust for donor to see if genotype will still have an effect.  
So if I want to analyse the effect of treatment on my chickens I should write the formula line like this: --p-formula treatment + room.  
And if I want to analyse the effect of room I do it the other way around.

is this correct?
