Hi!

You have to issue explicit BOND commands in tleap to connect the
residues back together after adding the TER cards.  If you need help
doing that, just say, but it's pretty easy, and there are good
examples in the tleap docs.

However, by doing so, even if I've solved the tleap problem, I have problems when minimizing the structure with sander (Amber). The monosaccharides don't remain bound to each other. Could you please help me solve this issue?
