Hi Guillaume-
I think you can also include subjects with visible motion artifacts, as long as you censor the TRs affected (or confirm that AFNI is censoring them automatically.) We create a list of artifact timepoints to censor when doing @epi_review. Usually it's only 1-3 TR's, and only with extreme motion (>1mm, roughly.) I'm always curious to hear what other labs are doing though...
Cheers,
Josh
