Administrative privileges are NOT needed to install the Linux binary distribution of Open3DGRID.

If you wish to determine the most appropriate version for your system, download choose_version (a small utility based on Dave Jones' x86info), open a terminal and type:

$ chmod +x choose_version
$ ./choose_version

Then, download to your preferred location the .bin installer matching your system. Run the latter by issuing the following commands:

$ chmod +x your_open3dgrid_version_setup.bin
$ ./your_open3dgrid_version_setup.bin

Inside the open3dtools folder you will find a bin folder containing the wrapper script, which calls the open3dgrid executable after properly setting the LD_LIBRARY_PATH. In fact, the open3dgrid executable has been built with Oracle Solaris Studio Compiler for Linux version 12 update 3 and linked with the Sun Performance Library. The Linux distribution of this compiler does not allow for full static linking of libraries, so the LD_LIBRARY_PATH has to be properly set in order for the OS to find the dynamic link library needed by Open3DGRID, namely If you invoke Open3DGRID using the wrapper script included in the bin directory, LD_LIBRARY_PATH will be automatically set for you.

Instead, in the open3dgrid folder you will find a README file, the license, the ChangeLog, documentation, some examples and utilities.

Open3DGRID depends on OpenBabel for file format conversions and atom type assignment.

Unless you already have the latest version of openbabel_for_open3dtools installed on your system, you will want to download also the openbabel_for_open3dtools_linux_setup.bin installer which includes all necessary dependencies for Open3DGRID, and install it in the same place where you previously installed Open3DGRID. Should you at a later stage decide to download and install another tool of ours which has the same dependency from OpenBabel, such as Open3DALIGN or Open3DQSAR, just install it in the same place where you previously installed Open3DGRID and openbabel_for_open3dtools, and everything will work out of the box as long as you keep the original arrangement of the directory tree.
