Hi Andrew,

After, few days of running the FDR analysis with the model you advised me to use, I am finding the same kind of results than before.
More annoyingly, I am also getting negative value of f-test when I am looking at the significant links.

I really do not get it! I checked my subject matrix, they are sparse and with nothing special (no NaN or Inf).
Any idea/ suggestion?

Thanks a lot for your patience.
Cecile
