<br>
it's resolution dependent. <br>
<br>
Say you are looking at ARG (or something similar with long side
chain), which has a few atoms sticking out of density, while the
other atoms are well placed into density. Then if you compute CC
for the whole residue it will still be high enough to mislead you
thinking that everything is all right with this residue. However,
if you compute CC per atom it will immediately red-flag these few
atoms that are not in density.<br>
<br>
Computing CC per atom actually makes only sense if density shows
you atoms, that is the data resolution is high enough. For
example, you would not want to compute CC per atom at resolutions
like 3A or so.<br>

<br>
phenix.real_space_correlation allows more fine tuning. In
particular it allows you to specify whether to output CC per atom
or per residue.<br>
