Hello,

Does anyone know of a reference discussing the effect of resolution on
the number of hydrogen bonds in a structure?  I think the number is less
precise and accurate at lower resolution but is there an estimate of error?

If we define packing density as the ratio of van der waals volume of a
protein over real volume, does it depend on resolution.  I do not think so
but is there a reference either way?

I would appreciate all replies.

Thanks.
