Hi Gabriel, I suspect you just need to do these steps here:
http://brainvis.wustl.edu/wiki/index.php/Caret:Operations/MapVolumeToSurface Viewing the Results To view the results: * Load the metric file created by the process into Caret along with coordinate and topology files. * Press the *D/C* button in the *Main Window's Toolbar* to display the *Display Control*. * Use the *Display Control's Page Selection* control to the the current page to *Overlay/Underlay - Surface*. * Set the *Primary Overlay Data Type* to *Metric*. If there are multiple columns of metric data, use the *Display Control* selection to select other mappings. For the flat surface, I suspect you are looking for more of a sulcal depth pattern (see attached capture). If so, make sure D/C Overlay/Underlay Surface *underlay* is set to surface shape, and the column is set to Depth. (You should have this if you used the pipeline. If you don't use the pipeline, Freesurfer's *h.sulc gives you something close.)
