I do have the multiple soil samples and I have given three treatment to these soil sample: T1, T2, T3. So I want to see the treatment effect on microbial abundance in these samples.
#[sample metadata columns are like this: sample_id Tissue Treatment Villages Region soil-01 soil T1 Menjana Rajshahi soil-02 soil T2 Khola Mymensing
could you please suggest me how I can design --p-formula for this analysis:
