Hi Doug, I'm trying to analyze my retinotopy data and visualizing in tksurfer.

I've been able to view the significance maps through: tksurfer-sess -a rtopy.self.lh -s sessid

But I've had issues displaying the polar angle data using the Configure Overlay tool. Specifically, I want to use the color wheel to assign colors to angles in order to help define boundaries between regions:

1) Do the angles range from -pi to +pi?

2)In the Configure overlay window, after I've clicked the 'Color wheel' radio button, I can't find the 'Apply' button that is supposed to be at the bottom of the window. Resizing the window doesn't work.

tksurfer-sess -a rtopy.self.lh -s sessid -map angle

tksurfer-sess -a rtopy.self.lh -s sessid -map angle.masked

Also, is there a guide on how to draw region boundaries using angle, polar, and fieldsign info?

Thanks very much. Michelle

Michelle, Can you give more details of what you are doing? How did you generate the files you are trying to load? doug

Dear Freesurfers, I'm having issues trying to display the polar angle data using the color wheel. Unfortunately, I can't resizing the Configure Overlay Display window. No matter what I try, I can't actually see the Apply button.

Any suggestions? Also, is there a quickie guide on defining the boundaries of visual areas?

Thanks. Michelle _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
