Dear Doug, thank you for the clarification. So to make sure, do you use this group_avg_area for each vertex also for building null distribution of maximal cluster size? The area values in .csd files are values of group_avg_area of cluster with maximal group_avg_area in each simulation step? Loo

It is quite confusing and took us some time to understand ourselves. When we create an average subject like fsaverage, we have to create a triangular mesh just like we do with any subject. This means that we have to assign an xyz to each coordinate. When trying to represent a group, this is not

Dear Doug, thank you very much for the support. I am quite confused by this info about correcting of area of fsaverage clusters. Could you please clarify to me the following: How exactly the values of lh.area, lh.white.avg.area.mgh of fsaverage were computed? How the cluster area inside mri_s

Dear FreeSurfer experts, I am using mri_surfcluster to compare results from PALM and FreeSurfer cluster extent inference. I came across several issues in mri_surfcluster I cannot cope with. 1. I observed that --mask option in mri_surfcluster does not prevent cluster to growing outside the mas
