Dear Anderson, I just want to make sure that i am implementing your answer correctly. Assuming that my TFCE result file is OneSampT_tfce_corrp_tstat1.nii.gz i should do: fslmaths OneSampT_tfce_corrp_tstat1.nii.gz -pval output1.nii.gz fslmaths output1.nii.gz -log 10 output2.nii.gz fslmaths output2.nii.gz -mul -1 output3.nii.gz fslmaths output3.nii.gz -thr 1.3 output4.nii.gz Is this correct? can i write it up all in one line? or should i make a short script that call all these commands one after the other? Thank you! NAvot
