Dear All,
Previously I ran a TBSS analysis with v1.1, and used randomise v2.0 to do the statistical analysis. Now, I just wanted to try the new version of randomise, v2.1, but on the identical data, design martix and contrasts, I got different results, e.g., much less significant results in voxel level in v2.1 than in v2.0. The command I used in randomise v2.1 was "randomise -i all_FA_skeletonised -o tbss -m mean_FA_skeleton_mask -d design.mat -t design.con -n 5000 --T2 -x -V".
I read the "what's new" about TBSS v1.2, which suggests re-run the TBSS analysis from the first step. Should I re-run the analysis on my data and then do the statitical analysis with randomise v2.1, or any other suggestions? Many thanks.
Best wishes,
Ling
