Hi Pete,
Well, what I'm thinking is that there are two options.
One is to extract the surface from Brainstorm with the data/values on it and import into SUMA, assuming the weird smoothing that alters the sulcification isn't imported along with it.
OR to export the data on the surface from Brainstorm as a NIfTI that's coregistered to the subject's anatomical used to generate the surface in the first place, then project that NIfTI data onto the SUMA surface as I've been doing with our fMRI data.
Do these seem like reasonable ideas? Is there something obvious to try that I'm missing?
Thank you! Veronica
