Environment Variables

   

Several environment variables are used by VMD to determine the location of certain files and directories. These variables are accessible to text interface through array env.   These variables include:

• VMDDIR :   The directory which contains the VMD data files (such as this help file) and architecture-specific executables. By default, this is /usr/local/lib/vmd.
• VMDTMPDIR :   The directory which VMD should use for temporary data files. By default, this is /tmp.
• VMDBABELBIN :   The complete path and filename for the program babel, which is used by VMD to convert molecular structure/coordinates files into PDB files which VMD can actually understand. If this is not set explicitly, the VMD startup script will attempt to find babel in the current path. If Babel cannot be found or is not installed, VMD\ will not be able to read molecular file formats other than PDB, PSF, and binary DCD files.
• VMDHTMLVIEWER :   The name of the HTML viewer (Netscape, Mosaic, whatever you prefer) that VMD should use to display HTML documents (such as this help file). By default, this is Netscape.
