Hi Sepideh,
do you mean pick the maximal activation over depths? The max is an unstable measure, and makes most subsequent statistical analyses invalid.

Hi,
I am rendering an analyze format img onto the fsaverage surface. I was wondering whether it is possible to specify the MAXIMAL depth of activation that is supposed to be projected onto the surface. Hereby I mean an ADDITIVE depth: The option --projdist (and also --projfrac) are not doing what I want. They lead to a translation of the projection surface into depth, but I seem to loose the more superficial activations. I know that my goal could be achieved in the older versions of FreeSurfer using --dmax for the paint command. So I wonder how I can do the same thing in the current FreeSurfer.
Thanks, Sepideh
