Hi,<br><br>I am trying to paint the functional significance map onto the surface generated from the antomical (monkey brain).  What I am doing now is using the following command:<br><br>&quot; tksurfer ${tmp_subj} ${hemi} ${cut_surface}  -overlay /space/data/stan/cooked/2010/100131CastorTEST2/MION/fmc_reg/H-vs-V/sig.256.reg.nii -overlay-reg ${reg_dir}/register.dat &quot;<br>
<br>the &quot;sig.256.reg.nii&quot; is the significance map and &quot;register.dat&quot; is the transformation matrix. <br><br>It looks like that the commands are doing fine, I see the signicance map on inflated surfaces.  However, I also see other tutorial that used mri_vol2surf to display the significance map.<br>
I wonder whether or not our method is not as good as mri_vol2surf. <br><br>I am asking this question also because we are creating ROIs from the surfaces. Now our ROIs (labels)  are only corresponding to a very tight layer of voxels surrounding the white matter. Shall I use mri_label2vol to include all the graymatter voxels surrounding the label?<br>
<br>Any suggestions would be very helpful.<br><br><br>Yang<br>
