Senility is, in fact, setting in.

It was a modified version of CAD! Sorry for the confusion.

To further compound the confusion, I am not sure if my solution is what
you are really looking for, although I suspect you should try it. What
we did was use an overall negative B-factor to achieve a sharpening
effect (Cell 119(3):393-405). Others had done this before (David
Borhani comes to mind)....anyway, it can be very, very useful.

Eleanor was kind enough to modify truncate years ago for me to do this -
I would guess the feature is still there.

Thanks again Eleanor!

Subject: [ccp4bb] B-factor sharpening in CCP4 or Coot

Hi,

I have a question for everyone. I wanted to up-weight my high
resolution terms in my electron density map by applying a B-factor
sharpening term. I have mtz files produced from DM and I usually use
Coot to generate my electron density maps. I was wondering is there
an easy way to apply a B-factor sharpening term in Coot? If not, is
there a program in ccp4 where by I can set the B-sharp factor?

Thanks

Jeff
