A way to check for non-unique coordinates?

I got the *Error: pairlist i_upper mismatch* and the *Warning: Not all atoms
have unique coordinates* for an equilibration simulation in the first step.
>From a previous discussion in the mailing list I think the problem is atoms
with the same coordinate in my restart.coor file. Everything looks fine in
VMD, so I used VMD to make a pdb file of the restart.coor file.

I just thought I would ask if anybody had any suggestions on how to check
for non-unique coordinates? I thought about writing a C programm, I'm
wondering if anybody has any readily available or in tcl script. Or how have
you done this in the past?

Thank you,
Diego A. Vargas
