Representing Scout data in Desikan-Killiany atlas

[mcardenas]

Thanks in advance for the help

Currently, there is not a straight forward way to do so in Brainstorm, as 3D representations are for data defined at the source level, rather than the Scout (ROI) level. But it can be done as indicated in this post:

Map values to brain subregions in 3D cortex display and generate heat map

Dear experts, I have data that each brain subregion is associated with a specific percentage value. Now I need to map these values onto the respective brain subregions of the 3D cortex display to create a heat map, where each subregion is represented by a single color. In particular, I am seeking methods to map the values to subcortical nuclei (e.g., thalamus and its subregions) and create the heat map. However, I have not yet discovered how to accomplish this in Brainstorm. I have also upl…
