Hi Donna, hm... by "copy metric file", you mean to save it as a surface_shape file? When I did that, and re-open it as a surface shape, it showed options of creating new columns (deformed Depth/ deformed Smoothed Depth/ deformed Folding (Mean Curvature)/ deformed Gaussian Curvature). In D/C, I set Secondary Overlay to Shape and chose one of the surface shapes, but nothing happened.
Also in Surface> ROI, I could not choose clusters, but one node. I think the problem is that I'm not "copying" into the right format. Could you elaborate on that? thanks!
