Hi,
I'm using Caret 5.3 and would like to map a functional data set (t-statistics) onto the surface. Initially my functional volume was aligned to the anatomical volume used to create the surface. Though the two volumes have different fields of view and voxel sizes, both images were centered around zero (0,0,0) and were in alignment in AFNI. However, when creating the surface, the origin of the anatomical volume was shifted to be (done within Caret following tutorial instructions) at the AC and then cropped (right hemisphere). So clearly I need to adjust the origin of the functional volume to match that of the AC adjusted surface volume. But simply copying the origin of the surface volume to that of the functional volume is not right, because the two volumes have different fields of view. I was hoping this is a common problem and there exists and easy solution. thanks, Brad Buchsbaum
