Hi All,

I tried the command you suggested Doug (recon-all -s subject -wmparc -cortparc2 -aparc2aseg).  It exits with an error because it cannot find the lh.sphere.reg file. The command and what is displayed after the command is executed is pasted below.

If you make a label file with the surface RAS coordinates of the
electrodes, you can run run mri_label2label specifying the same subject
as the source and target and --regmethod surface and --paint and it will
map the points to the closest surface point.

If you have an installation of FS 5.3, you can run
recon-all -s subject -wmparc -cortparc2 -aparc2aseg
I think this will work on a 5.0 folder. I would make a copy of your
subject before running it. It will regenerate the aparc+aseg.mgz file
