Hi Elaine,

I addressed the question to CCP4BB but il did not seem to interest anyone.
I state it again :

I wonder how much of an impact should there be on structure refinement, validation and, last but not least, molecular modeling, if we take into account the recent (2011) re-definition of the hydrogen bond made by the IUPAC.

Tough job, isn't ?

My guess is that Chimera should be involved.

Dear Elaine,
                Many thanks for the suggestion and reply. I will do as said
and will mail if any problem persists.
