Hi Rachel, yes, there is a difference if you compute SPC of the average thickness in an ROI or if you average the SPC computed on a vertex level. For the second, you can use long_mris_surf to map your third group to fsaverage and compute SPC, there is an option to write out the stack, then

[Freesurfer] longitudinal spc over an ROI

2016-09-16 Thread Rachel Romeo
Hi, I have 3 participant groups in my data set, all with 2 longitudinal time points approximately evenly spaced. I've run everyone through the longitudinal pipeline, and used the Monte Carlo simulation to find a cluster that differs in SPC between groups 1 and 2. Now I want to calculate the
