I meant the volume to surface mapping, so it sounds like your plan should work
fine.
Peace,

Thanks for the reply Matt.
I didn't quite understand what you mean by: " I would do your mapping in
individual subjects."
In case it was not clear, the tractography is of course performed in
individual subject space using the MSMAll surfaces in the subject
directory of the T1w folders. My
Thanks Tim and Michael,
I am thinking about doing some work with some statistics derived from
tractography (starting from the vertices on gray white matter interface
and then projecting those statistics onto their respective vertices) My
thought however, is whether the MSMAll (or functional

To explain further, the MSMAll registered surfaces have vertex indices
matched by nearby functional features, not by their position on folding
patterns. Creating a group-average MSMAll surface is essentially asking
the question "for this functional feature, where is it, on average". Based
on
Creating an “average-surface” is fine, and we in fact to that and provide it as
part of our “group-average” data (available for download from ConnectomDB).
But, those average surfaces are just a “back-drop” for overlaying/visualizing
the metric/cifti data, and aren’t intended to be used as a
