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. Web15 Apr 2024 · (TFCE; FWE corrected p < 0.001; nuisance co-variates: age, gender). D-F) B-ALS vs. healthy controls: The most significant changes were observed for increased MD, localized mainly in bifrontal WM including both CSTs, in some parts with overlapping RD increases. The FA contrast did only show a small cluster of decreased FA right …

WebAnalyses revealed a main effect of diagnosis on FA across all three groups (p tfce-FWE = 0.003). BD patients showed reduced FA compared to both MDD (p tfce-FWE = 0.005) and HC (p tfce-FWE < 0.001) in large bilateral clusters.
