text: user9890: I did gmx trjconv on GROMACS trr file to generate a .xtc file, and then used gmx dump and saved its standard output in a file. Then I tried to make a movie with VMD using the file. As a result, it does not work properly. The error in the terminal is as follows.
  gromacsplugin) Cannot read header fromm '/Users/kondouakira/mount/Lab/1ns_sim/md_0_1_noPBC3.trj', no error
  
  I use following command.
  gmx trjconv -s md.tpr -f md.trr -o md_0.trr -pbc mol -ur compact -b 1 -force
  gmx dump -f md_0.trr > md_0.trj
  
  
  user12054: No need to use gmx dump, you can simply load a xtc or trr trajectory in VMD using:
  vmd path/to/gro_file.gro other/path/to/trajectory_file.xtc
  
  As always you can also use the GUI to first open your gro file, then right click on the molecule and select Load data into molecule before selecting your xtc or trr file.
  After putting the representations as you see fit, if you want to export this as a movie (GIF, MP4, others...) you can go in Extensions -> Visualization -> Movie Maker. See Trajectories and Movie Making VMD official tutorial for more details.
