External Email - Use Caution

Dear Freesurfer experts,

May I ask how could I customize the color scale in TkSufer? The default heat scale is blue-red. Could I change it to other colors, such as green-yellow or blue-white-red (like gradient)?

Now I know how to customize the color scale in Freeview. The problem is in the 'custom' of Freeview I can not ignore zeros. Actually I'd like to display deactivation/negative value in 'light bule-white', activation/positive value in 'white-light red'. Any suggestions would be much appreciated.

Best,

lizhi
