Not sure, we don't use tksurfer that much anymore. Have you tried freeview? You can run freeview with tksurferfv and the same tksurfer arguments (makes it easier)

External Email - Use Caution

Dear Freesurfer experts,

I would like to modify the values of the colorbar scale to display results in the inflated surface with tksurfer, in such a way that displayed values in the colorbar range from the minimum t- value detected to the maximum t value detected. I have tried to use the -fminmax flag, but the colorbar scale shows values from 0 to the maximum t value. Is it possible to limit values of the colorbar scale to min-max significant t values?

On the other hand, is it possible to invert the colors of the colorbar scale (e.g., red for higher t values and yellow for lower t values)?

Thank you in advance.

Best regards, Marina
