I wish to simulate a FEP mutation in NAMD of a proline residue to a hydroxyproline residue (i.e. mutating a H into OH)
The converse (hydroxyproline to proline) is an easy process because this is simply the annihilation of H and the mutation of O into H (retaining the same coordinates)
My question: How does one write a hybrid pdb file containing the coordinates of both vanishing and appearing atoms when I do not the coordinates of the atom (H) that is to appear?
In the FEP tutorial we are always *given* the hybrid pdb file already (e.g. tyr2ala.pdb) and I want to know how this is created.
Any help on this would be appreciated.
