Dear FSLers.
Our cluster output _maxc_ from randomise of comparing two groups
difference of tbss is very asymmetric, i.e. more significantly only one
side, though the uncorrected tstat is more bi-laterally. Any explanation?
I tried to convert the vox_tstat (1-p image) to z-stats using ptoz and then
"cluster" the z-stats image through cluster command. The group difference
results was more or less like tstat image, i.e.bilaterally symmtric.
Would this approach make sense for doing the cluter-base thresholding ?
Thanks.
