Hi Giulia

once you have the vertex index on any surface (e.g. the lh.white) you can lookup that vertex on any other surface in the same hemi (e.g. lh.inflated). Probably the easiest thing to do is create a label file and sample it to the white surface. Then it will show properly on the inflated

Hello, I would like to prepare two figures in which I show the locations of depth electrode contacts located in the human insula (respectively left and right), on inflated surfaces.

I have identified each electrode contact with a vertex in either the left or the right insula.

Can these same vertices be used to locate the contacts on an inflated brain (e.g. with coordinated specific for the inflated surface)? What makes me a bit skeptical is that my contacts are located deep in the brain, so I am afraid that the alteration would be too large.

Thanks in advance for your help.
