WebStudy-wide FWE correction with TFCE. i.e., 1-p (FWE<0.05) images are produced that are corrected via a standardization algorithm and maximum TFCE values among all surfaces. The results can be exported as ply files and viewed using Blender or meshlab. Alternatively, the tmi result files can be converted to mgh or nifti.

For inference, the TFCE image can be turned into voxel-wise P-values via permutation testing (Smith and Nichols 2009; Li et al. 2024). Using TFCE for VBM studies has several advantages. TFCE allows the usage of smaller smoothing kernels, without worrying about …
