Hi Bruce,

Thanks very much for your email. Yes, I want to color each area with the same color accroding the Z scores, and on the fsaverage surface. I have one solution which transfer Z scores to RGB for displaying, but I think that solution would not be suitable for cases with both positive and negtive scores (I am thinking more about if it's possible to adjust this solution into my case). Hope someone here can help. Thanks.

Best, Xiangzhen

Hi,

...

I am doing a project with the Desikan-Killiany atlas. After some ROI analysis, I've got some values for each area. Now I want to display these values in the brain 3D space. The values are Z statistic scores, so there are both positive and negtive values (I want Z=0 to be in the middle of the color bar). In addition, I want to have a color bar about the plot. Attached please find one example data for the displaying. Please help if you have experience about this method. Thanks.

Best, Xiangzhen
