External Email - Use Caution        

Hi FreeSurfer experts,


I am trying to understand the Monte Carlo Z simulation in FreeSufer 
(mri_glmfit-sim) and have a question about the vertex wise /cluster forming 
threshold.


In the simulation, a vertex wise threshold (ex. -cache 3 abs) is set and the 
threshold is applied to a z map. Is the 3 threshold (p value of 0.001) 
converted to a z score using the z table before it is applied to the map?


Thanks!

Aylin
