Hi Hailiang,
I posted this several times and here is another one.. The exact formula
and all the related details are here:

(there is a small typo in the formula found by Lothar, but I leave it
for you to find -:) )
Also, here is ano
Hi,
I have a very simple question about the R factor. I was trying to
reproduce the R factor reported in the PDB file. I used phenix.fmodel
incorporating solvent model, anisotropic scaling etc to calculate Fc, but
frequenlty it doesn't match the PDB R factor.
Now I am wondering what is the scalin
Perhaps I was confused by the "refinement exclude" keyword which
explicitly says that atoms excluded from refinement will contribute to
the mask calculation. Thanks for the correction.
I
would still object to the zero-occupancy atoms on semantic grounds.
Partial occupancy means that an ato
I agree that zero occupancy is a bit ugly, but useful when not sure
whether you will ever see that LYS..
But I dont think it wlll displace bulk solvent - at least not in REFMAC
where an atom with occ=0.0 will not contribute to the atom map. And I
expect this is true for all other structure fac

There are several.
