Dear all, 
  <div>I am working with a cyclic protein and I am trying to make a figure with ccp4mg. I would like to know how to say to ccp4mg that the N and C-terminus are bound.... Although atoms are at a covalent bond distance, the chain is broken by ccp4mg...</div>
  <div>Many thanks in advance for your suggestions and help!</div>
