Hello, AFNI experts

I am running 3dRetinoPhase command with EPI functional data.
After preprocessing, I run the 3dRetinoPhase.....

3dRetinoPhase -exp BOLD+orig -prefix RESULT -Tstim 40 -nwedges 1 -phase_estimate FFT (I used the rotating wedge stimulation.)

In GUI, I can see the phase map (RESULT+orig) overlaid on BOLD+orig. I think that the RESULT+orig is showing the phase value ( "degree" ). It could be time delay.
For example, OLay = 180.0003 in GUI.

I am wondering what this value represent?
If a certain region has the phase value of 180, was the brain region activated when the wedge passed just in "the six o'clock position" ?? (We assume that the wedge started in the 12 o'clock position)

Thanks in advance.
