Sorry Dave. I was not clear. The previous files I sent you were the
"output" files written by the module ambpdb of Sander with the misplaced
TERs. My "input" pdb files with what I think are the correct placement
of TERS are shown below. Basically when I add the third metal CUB with
waters I get the misplaced TERS as shown in previous email. The systems
admin did increase the number of atoms/residues accepted by ambpdb and
recompiled the system, but he is very good and I doubt that he did
something to cause this. But if he could have caused this, what should
he look for in the ambpdb script? What is also very strange is that if I
save the three OR the two copper system in xleap (i.e using savePdb file
file.pdb) I again get a misplacement of a TER command, but in a
different location. Would it be better to send you my leap.log files for
these situations?

Note that the above file (which "works") correctly has a TER card after
the OXT of GLN 1072.

The above file (which, as I understand it, fails), is missing the TER
card
after OXT of GLN 1072. Could you try adding this to see if that helps?
....good luck...dac
