Re: [gmx-users] tpbconv subset

2010-05-24 Thread John Shultz
I modified the .mdp file, created a full system tpr, then ran it
through tpbconv, then ran mdrun using the original xtc. It says the
atom numbers don't match.


mdrun -rerun md.xtc -v -s lig.tpr
---
Program mdrun, VERSION 4.0.5
Source code file: md.c, line: 859

Fatal error:
Number of atoms in trajectory (37655) does not match the run input file (65)

 Modify the .mdp file the way you need to, create a full-system .tpr file,
 then run it through tpbconv.

 If you have a .tpr file, then the .mdp file is a step backwards.  You
 don't
 need it.

 Assuming you want to do some sort of re-run procedure, you simply have to
 run:

 mdrun -s subset.tpr -rerun original.xtc

 (where original.xtc is your trajectory file that contains the same subset
 of
 atoms as subset.tpr)

This time it appears that you have saved your whole system rather than the some 
other subset (ligand only?).  Check your xtc-grps to see what was written.

Re: [gmx-users] tpbconv subset

Justin,

Only problem is I need to change this parameter
energygrps

to track the energy on specific groups in the simulation. Is there a
way to modify the simulation parameters to track these energies?
