Hi @dts (and @mrgambero),
Thanks for the question! In a previous response, we showed how to convert the coef to log2 fold change. This is also something that we are thinking of implementing more clearly in the next major iteration of MaAsLin. We haven’t done it to date because it is confusing to implement/interpret within the multivariable infrastructure of MaAsLin. In the future, we are thinking of allowing a call for the main variable of interest within the model which will allow the results of a log2 fold change to be more interpretable.
I hope this helps!
