Hi Antonella,
From this command you wrote, you will have the t-map as well. Look at the folder. It should have files named tbss_tstats... Depends on your contrasts ...
For eg, if you have two contrasts (1,2), you will see six files after you run: randomise -i all_FA_skeletonised -o tbss -m mean_FA_skeleton_mask -d design.mat -t design.con -n 5000 --T2 -V
tbss_tfce_corrp_tstat1.nii.gz -- corrected p value
tbss_tfce_corrp_tstat2.nii.gz -- corrected p value
tbss_tfce_p_tstat1.nii.gz -- uncorrected p value
tbss_tfce_p_tstat2.nii.gz -- uncorrected p value for contrast 2
tbss_tstat1.nii.gz -- t value for contrast 1 -- that's what you wanted
tbss_tstat2.nii.gz -- t value for contrast 2
you can use following command lines to get the significant t map:
steps
(1) fslmaths tbss_tfce_corrp_tstat1.nii.gz -thr 0.95 tbss_tfce_corrp_tstat1_th95
(2) fslmaths tbss_tstat1.nii.gz -mas tbss_tfce_corrp_tstat1_th95 tbss_tstat1_masked
If you want to know the x,y,z for your corrected map.
(3) cluster -i tbss_tfce_corrp_tstat1.nii.gz -t 0.95 --mm
Hope these are helpful to you.
Cheers,
Yingying

Dear FSL experts,
Is theer a way to get the t statistics values in significant clusters from my TFCE results? For TFCE I was using the following command: design_ttest2 design 30 32
randomise -i all_FA_skeletonised -o tbss -m mean_FA_skeleton_mask -d design.mat -t design.con -n 5000 --T2 -V
Thank you for your time and your valuable support.
Best regards,
Claudia
