Hi Xara, Because you are in the enviable position of having high res T1 AND T2, you may be able to use the Human Connectome Project pipelines on your data, rather than this (older generation) caret-based myelin mapping script:
http://www.humanconnectome.org/documentation/HCP-pipelines/ This also has the advantage of writing output files in workbench formats, rather than older caret formats. I have a hunch that Matt Glasser will point you in that direction (he is probably at OHBM conference or on his way home). I confess I am not as familiar with this script as Matt is, but from what I read at the link you sent, it appears the maps are on the native mesh, rather than 164k. And I don't see myelin represented in the list of freesurfer_to_fs_LR output files here: http://brainvis.wustl.edu/wiki/index.php/Caret:Operations/Freesurfer_to_fs_LR/Output (These were independent efforts going on at roughly the same time.) You may already have considered the HCP pipeline route, but if not, it is worth a look -- you've got the T2's at the right res, which is often a hitch. I suspect myelin maps on 164k won't be your only benefit.
