after a round of adding/deleting waters, I have been using the Unix "sort"
command to re-order my waters by the X coordinate. something like this:

fgrep WAT junk.pdb |sort +5 -6 -n | pdb_reres -400 |pdb_chain \
|pdb_xseg -WAT |sed -e "s^O   WAT^OH2 WAT^g" >wat.pdb

where "pdb_reres" etc. are utilities to reset the residues numbers and such.
These are available by anonymous ftp from
indigo4.biomol.uci.edu , directory pub/schullersoft .  The "sed" command above
handles differences in naming waters between the graphics program (FRODO) and
the refinement program (Xplor).
