Hello,
I have been trying to perform a f-test on my TBSS data using TFCE option. The data consists of one group and 13 EV's. I am trying to see if all the EV's together have any significant correlation with FA.
But, for some reason I see that the corrp_fstat map is completely 0. I am using FSL version 5.0.4.
The following is the command used
randomise -i all_FA_skeletonised -o tbss_FA -m mean_FA_skeleton_mask -d design.mat -t design.con -f design.fts -n 5000 --T2 -V --fonly
Everything seems to run fine without throwing any errors, except for the fact that corrp_fstat map is completely 0. Under what circumstances could this be an expected output?
I have seen some previous thread with the same issue but could really spot the solution.
Best
Jay
