Hello! Thanks. I realized that vertices are added at the end when increasing resolution, what I was asking about is more about the details of the subsampling procedure, eg. what's the vertex number of the new vertex created on the edge between vertices n and m when doing a icosahedral subdivision step. But using mri_surf2surf works, thanks!
