How do I start KNIME from a standalone installation so the Schrödinger nodes can be run?

First, you must install the extensions into your KNIME installation and install the Schrödinger software. See Article 1084.

To use the Schrödinger nodes, the KNIME installation must know where to find the Schrödinger software installation. You can use one of the following methods to start KNIME so that it finds the installation.

(1) Use the KNIME startup script in the Schrödinger installation.

On Linux or Mac, open a terminal window, set the SCHRODINGER environment variable to point to the Schrödinger installation, then run the following command:

$SCHRODINGER/knime -knimeInstallDir path-to-standalone-KNIME

On Windows, you can add the path to the KNIME installation to the shortcut installed with the Schrödinger software. Right-click on the shortcut and choose Properties, then add -knimeInstallDir path-to-standalone-KNIME to the end of the text in the Target text box. Make sure that you don't replace the existing text, and make sure that you add a space between the existing text and the new text.

(2) Use the run command in the Schrödinger installation.

On Linux or Mac, open a terminal window, set the SCHRODINGER environment variable to point to the Schrödinger installation, then run the following command:

$SCHRODINGER/run path-to-standalone-KNIME/knime

On Windows, you can open a Schrodinger Command Prompt window and run the following command:

run path-to-standalone-KNIME/knime

(3) Create a script that sets up the environment, place it in your standalone KNIME directory, and run this script.

Examples of the script to use are given in the KNIME Extensions User Manual in the Schrödinger installation, and are also available for download for Linux, Windows, and Mac.
