Hi Elizabeth, I've never done this, I gather you want to project from surface-land to volume-land. (FSL will be able to process surfaces in cifti format, if it doesn't already, but this is a fast moving target that I don't track daily.)
I can't fire up Caret right now, but if you load the visuotopic paint files (e.g., using a scene from the basics tutorial), then do Attributes: Paint and look for an option near the bottom of the small list that suggests projecting to volume. Make sure your loaded midthickness surface is stereotaxically appropriate for what you want to do (http://brainvis.wustl.edu/help/pals_volume_normalization). If the FSL analysis with which you want to use this uses FNIRT for spatial normalization, consider using the Conte69 atlas (fs_LR mesh, http://brainvis.wustl.edu/wiki/index.php/Caret:Atlases:Conte69_Atlas), rather than PALS, because the latter doesn't have a FNIRT mean midthickness surface.
