Hi Koushik the vertices start out evenly spaced at 1mm, but various processing steps along the way change that. You can get a rough idea of how much area is devoted to each vertex by dividing the total surface area by the number of vertices, but of course there is a fair amount of variability, particularly in the vicinity of topological defects.

When Freesurfer outputs cluster summary files, it displays number of vertices (NVtxs). What is the size of each of these vertices. In other words, is there a standard correspondence between number of vertices and area of the cluster. > > Thanks > Koushik > > _______________________________________________ > Freesurfer mailing list > Freesurfer@nmr.mgh.harvard.edu > https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer > > > _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
