Quite recently appeared a nice work by
G.VRIEND and C.SANDER
named
QUALITY CONTROL OF PROTEIN MODELS: DIRECTIONAL ATOMIC CONTACT ANALYSIS
published in the JOURNAL OF APPLYED CRYSTALLOGRAPHY (1993)
volume 26 pages 47-60.
In that work the Authors revised all the currently used approaches to
estimate the quality of a structure, and as well introduce a new method.
I suggest it to anybody interested in the field.
