Hi, I'm puzzled by what you are trying to do. You say you have the original MTZ/MAP files. What have the original files got to do with it? EDSTATS requires the MTZ/MAP file calculated for the supplied model. The documentation states: "... the PDB file and the maps should all be from the same refinement job.". The refinement job referred to could be 0 cycles but the MTZ file must have been calculated from the PDB file supplied. If you have changed the PDB file then the original MTZ/MAP files will no longer be suitable. This means you have to supply exactly the same complete PDB file that you used to run the refinement job.
