comparison of refinement methods?

[Joan Pontius]

Can someone post a reference, or a site or something that
compares  and contrasts different refinement methods
used in protein crystallography?
ie, TNT, XPLOR, PROLSQ and SHELX?

ie, what parameters do they use, and what values/
weights do they use for the parameters.


thanks in advance,
joan
