Hi Anderson, Many thanks again. I am really interested in tbss_maxc_* result. How do I get tbss_maxc_* results then using randomise? Thanks.

What I really meant to type was without the --T2 option and with -c 3 option whether the results of tbss_tfce_corrp_tstat_* will be equal to tbss_maxc_tstat_* ? Thanks again for your time.

So, having --T2 and -c 3 in the same randomise call will give produce TFCE and cluster extent results, each on their own right. All the best, Anderson Am Mittwoch, 10.

If I use "randomise -i all_FA_skeletonised -o tbss -m mean_FA_skeleton_mask -d design.mat -t design.con -n 500 --T2 -V", I understand that the output is tfce based but if I use "randomise -i all_FA_skeletonised -o tbss -m mean_FA_skeleton_mask -d design.mat -t design.con -n 500 --T2 -V -c 3" then the results are cluster based, right? What I mean to ask is, whether tbss_tfce_corrp_tstat1 and tbss_tfce_corrp_tstat2 are equivalent to tbss_maxc_tstat1 and tbss_maxc_tstat2 if I use " -c 3" option? Thank you for your help.
