Dear FSL experts,
I ran TBSS analysis between three groups using randomise 5000 permutations and TFCE method. I followed all the steps mentioned in WIKI
I got at the end of the analysis, one large cluster represent the difference between the groups, as follow:
cluster --in=tbss_tfce_corrp_tstat1.nii.gz --thresh=0.95
Cluster Index Voxels MAX MAX X (vox) MAX Y (vox) MAX Z (vox) COG X (vox) COG Y (vox) COG Z (vox)
1 116346 1 87 90 22 89 104 82.5
How can I deal with the global effect between the groups, how can I approach the data in this case. How can I investigate if this global effect is a real difference between the groups, or its related to some technical issues? I highly appreciate any suggestions or advice?
John
