[gmx-users] Create a elastic network model -attach a spring between to atoms with force constant

[mohan maruthi sena]

Hi all,
             I want to create an elastic network model for a protein,
in which  i  have selected only c-alpha atoms(removed rest of the
atoms). To attach a spring  between  alpha atoms with some
force(spring) constant k , How can i mention this  in topology file ?


Thanks,
 Mohan
