Dear Donald and other gPPI users,
I was wondering if there is any (automated) way to select a different ROI for every subject using gPPI.
To be more clear, as it is possible within SPM, I would like to use a "floating sphere" within a structural mask (say DLPFC), with different location of the maximum peak within the mask, according to the global maxima, for every subject. With that, I would like to reduce to a sphere the number of voxels included in the calculation of the mean for each ROI.
I am guessing (did not find it in the version of the manual I have v1.0) I have to change something in VOI in the master template, but not too sure how and what…
Thanks in advance!
Best,
Yann
