Hi COOT users, I was looking at the COOT tutorial and saw the following explanation:
*"It can be educational (even useful at lower resolutions) to sharpen or blur a map. This can be achieved with the sharpening tool Calculate -> Map Sharpening.... By default, the maximum and minimum sharpness is +/- 30Å^2, this can be changed (in this case to 80) using:* *(set-map-sharpening-scale-limit 80)" * On COOT, I see it now goes to +/-200, meaning the current minimum and maximum sharpness is +/-75Å^2 ?? In the COOT mail archives I found the following reply by Paul Emsley: *It scales all amplitudes (whichever you chose when you read in the mtz file) by the application of a negative (or positive) B-factor. So the scale factor is a function of resolution and nothing more (at the moment).* *Paul.* So just to clarify, the sharpen/blur sliding ruler scales ALL original B-factor's by an identical value and the it ranges from +/-75?? Thank you, George
