[gmx-users] Program trjconv question

[PeiQuan Chen]

Dear gmx-users,

In the manual of Gromacs, It show that it is possible to select part of your trajectory and write it out 
to a new trajectory file, e.g. for leaving out the water from a trajectory of a protein in water.
  
I have done a MD of a protein in water, and I want to make a new trajectory files, which It only contains
the trajectory of the protein. So I think the trjconv program can help me, but I failed.
 
The command line I used to extract the trajectory of protein is following:

trjconv -f traj.trr -o newtraj.trr -b 0 -e 1000

But this command only make a trajectory file that contains both protein and waters trajectory.

Could anybody tell me help to resolve this problem?

Thank you in advance!  


Sincerely yours
----
