Hi Frank, EDS already does that. Even so, reproducing the R-factor does not prove that the map is reliable. See for instance 3frk for which the deposited dataset is much smaller and less complete than the one used for refinement. The map from EDS is therefore completely model biased. I only recently started looking for this problem of lower-than-reported completeness with. I have not found a lot of cases, but already too many. Fortunately, at least a few depositors deposited the rest of the dataset after I sent a bug report to the PDB (e.g. 3mbs).
