[gmx-users] position restraints

[Rongliang Wu]

Hello, gmx-users，
	i want to restrain two molecules, and i have added 

#ifdef POSRES
#include "posre_A.itp"
#endif

#ifdef POSRES
#include "posre_B.itp"
#endif

seperately in coresponding itp files, and add "define = -DPOSRES" to mdp file
 
but i got error

when i added

#ifdef POSRES_A
#include "posre_A.itp"
#endif

#ifdef POSRES_B
#include "posre_B.itp"
#endif

and how can i add both -DPOSRES_A and -DPOSRES_B to the mdp file.

define		=	-DPOSRES_A -DPOSRES_B

does not work

define		=	-DPOSRES_A 
define		=	-DPOSRES_B

will restrian only A

how to add both?


Regards

Thanks
