I would be very careful with this setup to make sure everything is ok.
you have combined Cartesian positional restraints, NMR restraints (not
sure what they are since it is your disang file), and tgtmd
restraints.
you should check the behavior of each of these in your data.
they can in principle work together, but it is not obvious how to
design the restraints to work together, the code may not have been
well tested for the combination, and there is also possibility for
restraint conflicts.
