Hello,
Unfortunately I did not see any significant voxels for the tbss_max_tfce_tstat1 at p0.05 or for the FWE voxelwise corrected ouput. Is it valid to interpret results from voxelwise uncorrected output - especially if you using only a part of the skeleton instead of the entire skeleton to do your analysis - more sort of a ROI analysis?
Thanks,

That's right, and tbss_tfce_tstat1 is the raw TFCE-enhanced image
(i.e. not p-values at all)

Yes. Did it work?
