Hi there, I'm not sure whether to post on here or freesurfer, but perhaps someone can help me anyway? I've been trying to use the surface tracking using Freesurfer and FSL using seed masks derived from fMRI activation clusters. Since these ROIs have been extracted from normalised images (i.e. standard MNI space) I'm unsure as to the best way to transform these into freesurfer conformed space. Any suggestions are greatly appreciated. Sarina
