Dear AFNI experts,
I'm sorry for asking again. Is it possible to calculate with AFNI the censor file of dvars values using a threshold of 0.5?
Furthermore, I would like to know what is the output that I can use as a regressor in the linear regression step, both in the case of enorm and in the case of dvars (if it is possible).
Any help is welcome! :)
Cheers,
Marina.
