[gmx-users] searching .tpr for position restraints

[David L. Bostick]

HI..

I would like to verify that I have input [ position_restraints ] correctly
in my topology file by viewing a resulting .tpr file and making sure grompp
has interpreted the things the way I intended.  I input the following ifdef
statement in my topology:

#include "ions_db.itp"
#ifdef RES_CL
; Position restraint for chloride PMF calculation
[ position_restraints ]
;  i funct       fcx        fcy        fcz
   1    1       0.00000      0.00000      1e-12
#endif

if I use the statement 

define = -DRES_CL

in the .mdp file, and gmxdump the resulting .tpr, what key word should I
search for in order to find the position restraint?  Where is this info
located?

Thanks,
David
