VMD User's Guide

will load the corresponding structure and coordinate files into the same molecule. On the Windowsplatform, one must preface the VMD invocation with the Windows start commandstart vmd molecule.pdb• -h | --help : Print a summary a command-line options to the console.• -e filename : After initialization, execute the text commands in filename, and then resumenormal operation.• -python : After initialization, switch to the Python interpreter before executing commandsin the file specified by -e (if any), and leave the text interpreter in Python mode.• filename : Load the specified file at startup. The file type will be determined from thefilename extension; if there is no filename extension, and the filename contains 4 letters, it isassumed to be a PDB accession code and will be loaded accordingly; otherwise the format isassumed to be PDB.• - filename : Load the specified file using the given filetype.• -f : Load all subsequent files into the same molecule. This is the default. A new moleculeis created for each invocation of -f; thus,vmd -f 1.pdb 2.pdb -f 3.pdb loads 1.pdb and2.pdb into the same molecule and 3.pdb into a different molecule.• -m : Load all subsequent files into separate molecules. The -f and -m options may be specifiedmultiple times on the command line in order to load multiple molecule containing one or morefiles.• -dispdev < win | text | cave | caveforms | none > : Specify the type of graphicaldisplay 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. Thisis useful with -display machine:0 for remote display of the forms when the CAVE usesthe local screen.– none: sameastext.It is possible to use VMD as a filter to convert coordinate files into rendered images, by usingthe -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 thenumber of pixels from the lower-left corner of the display to the lower-left corner of thegraphics window.• -size x y : Specify the size for the graphics display window, in pixels.172
