‚ÄčThose are NetCDF trajectories, not ASCII mdcrd files with box information.
 -crdbox tells VMD to treat the file as an ASCII mdcrd with box info.

You can either name all NetCDF files with the suffix ".nc" (which is
automatically recognized by VMD and does not require a format flag) or you
can use the "-netcdf" format flag for VMD.

Converting to text format would almost defeat the purpose of NetCDF
trajectories in the first place...
