I had a similar error when using CentOS on VirtualBox. The error came from an error in the OpenCL driver. Are you running a virtualmachine? If not i would advise trying a different graphics driver. As to the CentOS/Ubuntu choice. I would go with CentOS as it seems more stable/constant and is more e

Hi Franz, I just programmed a fix into mri_surf2surf. What platform do you use? As for the shift, you would not expect them to line up. In fact, that command line does not make a lot of sense. What it is doing is mapping the xyz coordinates in the native space to a new tesselation. The xyz co

Hi David the subject's ?h.sphere.reg file contains the list of locations on the sphere of each subject. Mapping to another subject would involve looking up the closest set of vertices on the target subject for each source subject vertex. mri_surf2surf can do this I believe. cheers Bruce On T
