Hi, Neuro-
I understand that question-- the important point to note is that the std.* meshes in SUMA are named that way because they are **standardized**: that is, the std.60.* meshes across subjects all have the same number of nodes, and a node of a particular index *should* correspond to the same physiological location (plus/minus some registration error) across all the subjects. The same is true of the std.141.* meshes, just with a higher number of nodes per brain. The std.60.* meshes correspond roughly to a typical spacing of EPI volumetric data, and the std.141.* meshes correspond roughly to a similar spacing of typical anatomical volumes.
You have used different templates to identify node locations, sure, but each of those meshes were standard, std.60* meshes, so the same node location should be identifiable. And therefore, you can take those node indices to any other std.60.* mesh and talk about it equivalently.
Hope that helps.
