Hi, there is an example on the page I linked to. Look for the code in the gray box that refers to randomise. You can probably copy and paste that exact code if you are in the stats directory of where you ran tbss. There is also a link on that page to the randomise wiki page that further explains its usage. You could also type 'randomise --help' on the command line. Rujing Zha <[log in to unmask]> wrote:
If you want to run statistics on skeletonized FA data, you should use randomise, as described on the page for Tract-Based Spatial Statistics:

Randomise will apply the appropriate corrections.

Subject: [FSL] correction about regression result of whiter matter and behavior data by fsl_glm
Dear fsl users,
I have done the multiple regression analysis by fsl_glm.
fsl_glm -i all_FA_skeletonised.nii -d design -o my_result --demean --out_p=pvalue
Do I need to correct the pvalue?
Thanks!
All the best.
