>please report the bond length and angle rmsZ next to (or instead of) the
rmsd in Table 1. 

 

'Instead' alone is also not enough - if in a  normalized statistic you do
not know what you normalized against - that is, the variance or esd of the
target distribution - you do not know what Z means. For example, I could
override the default set of my target rmsd in Refmac to what I want in order
to manipulate the resulting model rmsZ. 

The absolute rmsd value alone also does not tell you about the underlying
target variance. A bond length rmsd of 0.04A would make you cringe but only
because you assume you know the unrestrained or true target rmsd of about
0.02A). One reason why the restraint target table in the PDB header is
useful.

 

I think both values, rmsd + rmsZ, or rmsd and target variance or esd, are
necessary  for getting the complete picture.

 

Best, BR
