Multi-Modal Integration, Part 1: The tutorials also describe some of FreeSurfer’s tools for registering volumetric datasets, performing group analysis on morphology data, and integrating multi-modal output with FreeSurfer overlaying color coded parametric maps onto the cortical surface and visualizing plotted results.
Then you’re prompted for the number of vertices you want in the final cortex surface. You can switch between the two views with the button “Identify regions with colors” in the toolbar on the right of the scouts list.
