Dear Amber Users.
I am running nmr restraints during my dynamics runs in sander. When I look
for the NOE violations in the out put file generated, I notice I have
violations between atoms that have no constraints placed on them. Here is a
small part of my out put file:
First atom Last atom curr. value target deviation penalty

In the first line, it denotes a problem between two carbon atoms that are
connected with in aromatic ring. The second line shows a violation between
a carbon and oxygen atom that are separated by more than 8 covalent bonds
and have no NOE constraint between them. Also, I have no idea what the * in
front of the atoms names mean, as I have used no * in any atom names.
Thanks for any help.
