Re: [ccp4bb] odd request: add phase error linearly with resolution

2010-03-19 Thread Bart Hazes

Hi Francis,

Check out the CALC command in sftools. It allows you to apply quite a 
number of mathematical operations on MTZ column data, including phases. 
It also has built-in funtions to return the resolution of reflections 
which you can use in your calculation. CALC HELP should explain how to 
use it.

Hi all

I'd like to add a phase error to my PHIB's and FOM's (experimental phases) that 
increases linearly with higher resolution.. it's akin to taking good phases and 
making them bad. Any approaches on how this can be done?
Thanks
