[modeller_usage] Helix Packing:Docking?

["David Piper" <>]

Modellers,

  I would like to add a single helix to an existing 
model.
  I have a set of distance restraints to orient residues 
on the helix to be added to the existing model.
  What sort of approach might be recommended here?

  Should I simply build a the additional helix ab initio, 
and then remodel the existing model + added helix based on 
the existing model + the built helix and distance 
restraints?

  Is there a way to simply add the new helix to the 
existing model by addition + distance restraints?

  Thanks,

  David
