Hi all, I want to know difference between vertex-wise and cluster-wise in Groupanalysis. Can I just think vertex-wise are uncorrected P-value(which is the same as voxel-wise value) and cluster-wise value are the vertex population which are survived after a specific threshold correction? Thanks. All the best.

yes, a second p-value is computed for the population (cluster) and clusters are kept if their p-value is less than a certain threshold (usually .05)
