[gmx-users] forcing structure

[Osmany Guirola Cruz]

Hi people,

  This is may problem :-)
I have 2 PDBs of the same molecule(diferent 3d structure) but the first
one only have the CA of the molecule ... then i want to force my second
structure(whole protein) to fit the first(CA only) how can i do this?
can i use MD?

Thanks

Osmany.
