Water_pekpik [pekmol] [zone] [solmol] [first resname]
This commands combines Water_init & Water_add. The command will go through the output of a PEKPIK run, and prompt you to place a water molecule at each peak in the difference Fourier. All you have to do is accept or reject the proposed water positions, by picking on Yes or No. The command expects that you have already read in the output list from a PEKPIK or PEAKMAX run into an ordinary O molecule. Peak searching programs will usually output the peaks in a standard (RD or PDB) format, and can thus be read into the O database using Sam_atom_in.
