Hello all,

I'm in the process of mapping some non-FreeSurfer derived outcomes to a curv 
file containing the vertices of the pial surface mesh. I have values at roughly 
100 vertices, leaving some 37000 with 'nan'.

I then run an intra-subject surf2surf command in an attempt to interpolate 
between vertices for which I have values. The problem is that the NaNs pull the 
existing values down, resulting in a smearing/dilution of my outcomes.

Is there any way to interpolate and make the intervening vertices purely a 
function of nearby vertices for which values exist?

Thanks,

John
