Dirk, - Imagine a (not very uncommon, unfortunately) situation when someone obtains the final model and Fcalc, and then, right before the PDB deposition does a final check in Coot, and moves/removes a few atoms (a few waters, or instance) here and there. Or may be does a real-space fit of a

As a relatively inexperienced scientist, I find this discussion fascinating. I wonder if NMR and EM people are also worried about depositing enough modeled info to allow back calculation of data. Regarding the original discussion of whether to deposit riding hydrogens used in the

Very interesting discussion. I wonder if the inexperienced user of PDB really exists? I don't know anyone off-hand who would really make use of information from hydrogen positions but not understand the issues. Although I hear they have been sighted in the Everglades
