It is computed from the area of the triangles in the cluster. Actually, it is computed from the mean area over the group used to create fsaverage. Not sure what you mean by a standard algorithm doug

Dear Freesurfers,
When I do the Monte-Carlo simulation after mri_glmfitbetween my groups, I get an output summary file for each of my contrast. In that summary file, there are multiple columns for coordinates, threshold values, number of vertices and size (mm2). My question is, how is this area in mm2 calculated? Is it from the number of vertices? If so, is there a standard algorithm for arriving at the area?
Thanks in advance
Koushik
