A rather simple but effective way is to make an index which contains 1/4 of your protein file. Use trjconv with -center tric -pbc whole/mol to center that 1/4 of your protein and output the whole protein.

Hi Bob,

You could try -pbc cluster. If that doesn't work, it'll be difficult.
The option -pbc nojump will only work on continuous trajectories.

Cheers,

Hello everyone,
I'm trying to visualze the conformations of a ssDNA molecule obtained from a REMD trajectory. As expected, there are parts of the simulation where the oligomer is broken due to the PBC wrapping. I've been trying to fix this with trjconv. However, the -pbc nojump option doesn't work - it actually makes the
broken portions of the molecule worse and gives a terribly distorted
trajectory. Since the REMD trajectory isn't continuous (i.e. there are
instaneous jumps in the coordinates associated with REMD swaps), the nojump option may have problems. Does anyone know of any other way or other tools that
I could use to reassemble my broken DNA strand?
Thanks,
Bob Johnson
