Hi Phiroz,
I'm not sure I understand, but I think what you could do is create a volume representation of the grid, then sample it onto the surface with mri_vol2surf

Hello,
I have been trying to figure out if it is possible to overlay a grid on a surface (such as the regular non-inflated pial surface). I would like the grid to ignore the cortical convolutions and follow just the overall curvature of the cortex.
I am trying to represent a grid of electrodes on the surface of the cortex, as would be placed in the operating room for surface cortical recordings (ECOG). Is there a way for me to do this?
Thanks for your help.
