Hi All, Just came across a problem with fslmaths -tfce, I used the following comment fslmaths inputfile -tfce 2 0.5 26 outputfile and the output is always all zeros, also tried to play around with the E, H, and connectivity parameters as well as -odt float but same result always. I uploaded my file with the reference 768449. Please kindly check and advise.
