External Email - Use Caution Dear freesurfer team,
I want to overlay the activation map that I got from SPM on the inflated surface. The command I use is: "mri_vol2surf --mov spmT_funcmap.nii --ref subj01/mri/orig.mgz. --reg tk.dat --hemi rh --o flodername" in which, I got the registration file (tk.dat) by aligning my functional mean image to the orig.mgz in tkregisterfv. now the problem is when I overlay the activation map on the inflated surface, I can only see the voxels with positive t-values. I can't see the negative ones. I cannot change the threshold values provided by "configure overlay" to negative values. Also, changing the "z-score" option next to the overlay configuration doesn't make any difference. can you help me with this, please? Thanks a lot, Atena
