Hi Doug, Thank you for your quick answer. However, there are some points that are still not clear for me: 1-I would like to know also the correlation value (r-pearson; Cth-Variable) of my significant cluster. This is something that I can get directly or I have to do some additional analysis? If yes, which ones??
2-I would know the intercept of this cluster. 3-I’m using mri_segstats to get the average slope, I use: mri_segstats --seg mc-z.abs.th13.sig.ocn.mgh --sum proof But with this I only obtain the NVtx, I think I’m missing something….

(BIDMC - Neurology) CC: freesurfer@nmr.mgh.harvard.edu Asunto: Re: [Freesurfer] CORRELATION VALUE Hi Cleo, the mc correction will generate a segmentation file (something like cache.th20.abs.sig.ocn.mgh). The value at each vertex/voxel in this file correspond to the cluster that the vertex/voxel belongs to (if any). You can use this as the segmentation for mri_segstats and specify the gamma.mgh from your slope contrast to give you the average slope in each cluster. doug cgo...@bidmc.harvard.edu wrote: > Hi all, > > My design is very simple: 1-group,1-variable 2-nuisance (age,gender). > I just want to see the correlation between Cth and my variable. > I obtain one cluster after mc-correction.
