Hi Kai, The results I found look fine: - With EBs: https://dl.dropboxusercontent.com/u/2785709/outbox/mailinglist/kaiwang/eb_vox_tstat_uncp_c3.nii.gz - Without EBs: https://dl.dropboxusercontent.com/u/2785709/outbox/mailinglist/kaiwang/noeb_vox_tstat_uncp_c3.nii.gz The config files for these two runs are attached. I wonder why you have zstat files, and not ztstat or tstat. I'll run again in the afternoon with the -zstat option and compare.
