External Email - Use Caution        

Hi there,
 
I would like to analyze clusterwise correction for multiple comparisons using masks (exsample; superior frontal cortex and middle frontal cortex).
I know that "2spaces" means adjust p-values for two hemispheres as follow; mri_glmfit-sim --glmdir lh.gender_age.glmdir --cache 2 abs --2spaces.
If I use the masks such as the superior frontal cortex and middle frontal cortex, how do I do? 
 
Thanks,
Gwang-Won
