License for OpenEye Toolkits

A license file from OpenEye, Cadence Molecular Sciences is required to run any OpenEye toolkit. A license file can be requested/obtained by contacting OpenEye at sales@eyesopen.com.

At startup, the toolkit looks for a valid license in the following default locations:

  • In a file specified by the environment variable OE_LICENSE. Example commands to set the environment variable:

    • Linux/UNIX and MacOS:

      export OE_LICENSE=/home/USERNAME/oe_license.txt

      This can be executed in a shell prompt, or added to the user’s ~/.bash_profile. If running zsh, add to the user’s .bash_profile and then include .bash_profile in the user’s .zshrc.

    • Microsoft Windows:

      setx OE_LICENSE C:\Users\USERNAME\oe_license.txt to set the environment variable permanently using Command Prompt, or SET OE_LICENSE=C:\Users\USERNAME\oe_license.txt to set for the duration of the session using Command Prompt. $env:OE_LICENSE="C:\Users\USERNAME\oe_license.txt" to set the environment variable using PowerShell.

  • In a file named oe_license.txt in the directory specified by the environment variable OE_DIR.

  • In a file named oe_license.txt in the user’s platform-specific local OpenEye application data directory. The location of this directory is detailed below:

    • Linux/UNIX:

      ~USERNAME/.OpenEye

    • MacOS:

      /Users/USERNAME/Library/OpenEye or ~USERNAME

    • Microsoft Windows:

      C:\Users\USERNAME\AppData\Local\OpenEye

  • In a file named oe_license.txt in the current working directory
