Hi!

I filtered the table from the moving pictures tutoriall by BodySite='gut' and I wanted to perform a linear regression summary with gneiss (qiime gneiss ols-regression).

My issue is that when in the 10.fold cross validation I didn't have any value in my Rsqueared, appearing as "nan".

Why this happen?

Thanks!!

If you look at the summary - there are only 8 samples -- you can't do 10 fold cross validation with only 8 samples.

Not sure what you can do with 8 samples - so this is expected to break.
