Dear Alfonso,

I am trying to run an roi-roi analyses (76 regions) using;

1) un-normalised using u- prefix fmri scans and s- prefix structural
2) normalised using w- prefix fmri scans and w- prefix structural
3) smoothed-normalised using s- prefix fmri scans and w- prefix structural

Is this correct, when i use s- prefix fmri scans, I get a message stating cannot find unsmoothed data?

I am doing this to investigate the differences these have on the fmri connectome.

Thanks for your help.

Peter
