Hi all,
When I do a group analysis and check significant clusters after performing a Monte Carlo, I see significant areas that were NOT significant before doing a multiple comparisons correction. Specifically, after Monte Carlo, the parstriangularis is significant, while this area was not significant in the first place (before Monte Carlo).
I'm confused; how could that be possible? Am I doing something wrong?
Thank you!
Anita
Hi Anita, I don't think it is possible. Are you using the same voxelwise threshold in both simulation and visualization? Are you sure you are looking at the same contrast? doug
