Hi Doug,
I see. My eccen run has 8 cycles of an expanding ring and each cycle take about 64 sec. So in general the color "red" would show the average of the 8 cycles for the first let say 10 sec. I know from my protocol which eccen (1°-12° per hemisphere) was shown when, but how can I exactly find a area of a specific eccentricity on my surfce without using the color wheel?
I just would like to draw a label consisting 1°-5° in the visual field.
Can you recommend me another strategy?
Best,
Erhan

Hi Erhan, the results are collapsed across all time points, so no color represents a particular time point. The colors in the color wheel are hard to interpret, which is why I recommend against using the color wheel. If you click on a point, I believe the value (phase) will be displayed in the control panel. doug

Dear freessurfer experts,
I created my polar und eccen maps using the retinotopy pipeline. I also visualize them using the the rtview command on the inflated surface. But how can I interpret the colors (red to blue in the RYGB Wheel) in my eccen map? Which color refers to which timepoint (volume) of my functional run?
Best,
Erhan
