Hi Gabriel, More detail on how you "created surfaces from my own template" might help here, but let me extrapolate and provide information that might be relevant.
I assume you want the Brodmann parcellation in the form of surface-based paint/label or border form (i.e., the kind of thing shown in the Caret tutorials). These are available on our atlases, e.g., the PALS-B12 and Conte69/fs_LR atlases. If you have your own surface-based atlas, and you want to bring the paint/borders David van Essen generated to that atlas, then you will need to register your atlas to one of ours. If you have a mean midthickness surface for your atlas, then you can use it, along with less folded configurations (e.g., inflated, ellipsoid, spherical) to draw registration borders and use surface-based registration to get the two atlases in as close correspondence as possible. If you haven't done it before, it's not the easiest thing, but it's not as bad as, say, segmenting post-mortem brains. There are other anatomical atlases out there in volumetric form (e.g., automated anatomical labeling / AAL ; the Harvard-Oxford cortical/subcortical atlases (http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/Atlases). Depending on how hard it is to get your surface in the same stereotaxic space as these atlases, they may or may not be helpful. If you decide to go the surface-based registration route, then you will need a spherical configuration of your atlas. I don't know of a more current tutorial than this one: http://brainvis.wustl.edu/wiki_linked_files/documentation/Caret_5.5_Tutorial_Segment.pdf I hope someone will speak up if he/she knows of a more current one.
