        Hi to all, my name is Gerard Pujadas and I wonder which is the
difference between this two concepts which often are in the same PDB file:
R VALUE and FREE R VALUE. Which may be used as a measure of the refinement
quality of a protein X-ray structure. Please reply soon.

        Thanks in advances. Yours sincerelly.

        Gerard.
