I may need exact height data for reversing Y-axis to do exact mapping

I found the Y axis need to be reversed
Here's why:
Look at the initial of fixation we would find it locates at the down-left on the map.
But our trial begins from the top-left.
I figure it was the Y-coordinate got reversed.
So I made some overlapping, but I still found some obvious mismatch on ROI map.
Since I only resized the graph manually.

Do we have a specified region so that I can know how much I have to do conversion?
Like 800-y=y"
Y" is our desired correct y-axis. 800 is the actual height of our trial height.
