[phenixbb] B-factor map sharpening

Hi Everyone,

just a quick notice: the most recent version of PHENIX


has an option for electron density map sharpening which might be 
important for low resolution maps improvement.

This is available from the command line


and from the GUI as well.

Please let me know if you have any questions.

The optimal B-factor sharpening value is determined automatically 
although the user can provide his/her own value.

The above tools allow you to compute any amount of maps, so I would 
recommend computing at least two: regular amp and B-factors sharpened.

This is a new option so I would appreciate any feedback from those who 
got interested and tried it. Please let me know any bugs (should you 
find any) or any suggestions.
