Hi Yawu

we have tools for mapping G/W contrast and CNR, but of course that
presupposes that our surfaces are in the correct location (more or less).
You can for example use vol2surf to sample at negative and positive
proj_dist and compute this kind of thing, or I believe Doug has some
binaries that do it for you

cheers
Bruce
