Anyone knows of any way to convert from a NWChem trajectory file to anything VMD can read, for example Amber, Gromacs or NAMD trajectory format?
Thank you.

Hi Diego,
What dynamics module are you running. The Car-Parrinello ab initio MD generates a xyz based motion file that can be read by VMD. For classical MD you can convert the trj trajectory file into the same format, see http://www.nwchem-sw.org/index.php/Analysis#Trajectory_format_conversion for details.

trajectory format issue
|
Hi to all,
I've not understood how to convert my .trj file (output of a MD run) into a more easily handled format like .pdb or .xyz.
I've the link reported above, however the following error is reported:
Last System Error Message from Task 0:: No such file or directory
0: ARMCI aborting 0 (0).
system error message: Illegal seek
No trajectory is written (just a junk fort.69 file). What could I do to obtain my pdb/xyz file?
Thank you in advance.
Francesco

| The analysis module can convert NWChem trj files into Amber crd, Discover arc or Charmm dcd files. See the 'copy' directive in the trajectory file conversion section. Individual frames out of a trajectory can be converted into pdb or xyz format using the 'write' directive.
