I have significant group differences in volume (controls > patients) for one of the clusters (say C1) - calculated after permutation test using PALM, which gives me following outputs:

*_clustere_tstat_fwep.mgz (this is significant at p < 0.05, number of voxels = 1105)
*_clustere_tstat.mgz
*_dpv_tstat_fwep.mgz
*_dpv_tstat_uncp.mgz
*_dpv_tstat.mgz

I was wondering if there is a way to calculate volume values of C1 for each subject (i.e., controls and patients).

Thanks.
