VMD Unix Command-Line Options
When started, the following command-line options may be given to
VMD. Note that if a command-line option does not start with a dash
(-), and is not part of another option, it is assumed to be a PDB
filename. Thus, the command
vmd molecule.pdb
will start VMD and load a molecule from the file molecule.pdb.
- -h | -? :
Print a summary a command-line options to the console.
- -e filename :
After initialization, execute the text commands in filename, and
then resume normal operation.
- -psf filename :
Load the specified molecule (in PSF format) at startup. The PSF file only
contains the molecular structure; a PDB or DCD file must also be specified
when this option is used.
- -pdb filename :
Load the specified molecule (in PDB format) at startup.
- -dcd filename :
Load the specified trajectory file (in binary DCD format) at
startup. The DCD file only contains atomic coordinates; a PDB or PSF
file must also be specified when this option is used.
- -dispdev < win | text | cave | caveforms | none > :
Specify the type of graphical display to use. The possible display devices
include:
- win: a standard graphics display window.
- text: do not provide any graphics display window.
- cave: use the CAVE virtual environment for display,
forms are disabled.
- caveforms: use the CAVE virtual environment for display
and with forms enabled. This is useful with -display machine:0
for remote display of the forms when the CAVE uses the local screen.
- none: same as text.
It is possible to use VMD as a filter to convert coordinate files
into rendered images, by using the -dispdev text and -e options.
- -dist z :
Specify the distance to the VMD image plane.
- -height y :
Specify the height of the VMD image plane.
- -pos x y :
Specify the position for the graphics display window. The position
(x,y) is the number of pixels from the lower-left corner of the
display to the lower-left corner of the graphics window.
- -size x y :
Specify the size for the graphics display window, in pixels.
- -nt :
Do not display the VMD title at startup.
- -startup filename :
Use filename as the VMD startup command script, instead of the
default .vmdrc file.
- -debug [level :
Turn on output of debugging messages, and optionally set the current debug
level (1=few messages ... 5=many verbose messages). Note this is only useful
if VMD has been compiled with debugging option included.
