As long as the distance between atoms 1273 and 3839 is between r2 and r3 (i.e.
between 1.8 and 4.0 angstroms) you will have a zero restraint energy. I
suspect that this is what you are seeing.

This indicates that your restraints were read in. To get more debugging
output, add a LISTIN=POUT line in the restraint section. That will give
you detailed info about all the restraints that are being used.

...good luck....dac
