Dear Friends:
In fMRI, when we state stats threshold, we usually say; voxel level
threshold < .01 (or .05), not corrected, extent threshold p < .05
corrected. In tbss, if I use randomise -c to correct multiple
comparisons, the voxel level threshold is determined by the t value
after the -c option (my understanding). My question is how to
calculate the t value corresponding to voxel level p < .05 or p < .01?
