There is not a straight-forward way to do it as mri_glmfit-sim only takes a clusterwise p-value threshold. You can change that until you get 20 voxels.

Hi Everyone,
How may I threshold the sig.mgh (p<0.001) with a cluster extent K > 20 voxels? Is it possible to do this in Freesurfer?
Thanks.
Best Wishes, Elijah
