Hi, After I ran the qdec and analyzed my data(cortical thickness). I have two questions. First, after I display a plot of the data for a particular vertex by left-clicking on a point while holding down the Ctrl key, it shows a plot and its plot window shows this vertex's surface coordinates. What model is the surface coordinates used? Second, after analyzing the thickness, it shows the color bar's scale in p-value. How do I do to change the scale from p-value to mm? .
