External Email - Use Caution

Hi! Jumping in on this, since it has come up many times but is without a solution so far: the issue is that the color code is now mapped onto a straight color bar, not a circle. At the same time, it is not documented what color refers to which angle. That makes it very difficult to work with this kind of color bar. It would be very helpful to reintroduce the circle, and to explicitly document how angles are mapped to colors. Thank you! Caspar

When you say it is "linear" do you mean it does not wrap-around?

Hello freesurfer community,

I am trying to setup a retinotopy pipeline. I have analysed pRF data generating polar angle and eccentricity maps which I project onto an inflated surface / flattened surface in freeview.

Is there a way to display a circular/cyclic colour map (for the polar angle data) in the overlay screen?, the existing 'colour wheel' option seems to be linear?

Thank you!

Best, DV
