Hi Michael you can use either --projfrac-avg or --projdist-avg (dist I guess if you want to specify 10mm). Note that this is an average along 1D (the surface normal direction), not in a volume window cheers Bruce On Wed, 27 Feb 2019, Michael Jordan wrote: External Email - Use

External Email - Use Caution Hi Bruce, thank you it worked! Another short question: I want mri_surf2vol to assign the average of all volume voxel values within 10 mm to the corresponding vertices. So if there is only one voxel value greater than zero in the volume, all vertices

Hi Michael you can use --regheader, which uses the ras2vox matrices to compute the registration (which is also what freeview does). cheers Bruce On Mon, 18 Feb 2019, Michael Jordan wrote: External Email - Use Caution Hi, i would like to sample the t-values of a SPM

External Email - Use Caution Hi, i would like to sample the t-values of a SPM output volume (spmT_0001.nii) onto the pial surface of the same subject. The volume is already aligned to the surface files (so if I view the volume as well as the surface files in Freeview they are
