[phenixbb] coot and mtz interpretation

[Matthew Franklin]

Hi Heather -

 From your Coot window, you can go to Edit->Preferences, then select the 
"Map Colours" tab in the resulting window.  You should see radio buttons 
for "Coot colours" and "O colours".  The way these work is that you 
select the desired colo(u)r for the positive difference density (e.g. 
green).  The negative contour is then 120 degrees ahead (clockwise) on 
the color wheel if you choose Coot colors, or 120 degrees behind if you 
choose O colors.

It looks to me like you want positive to be green, and negative to be 
red.  So I think you want Coot colors, and positive set to green.  At 
the moment, it appears that you have O colors.

I have no idea if your selections will be kept the next time Phenix 
opens a window for you.  Probably not.

Hope that helps,

Matt
