Mae-To-SD node showed an error message


An error message “Execute failed: SCHRODINGER variable not set” was shown after I tried to run the titled node on Knime 4.1.1, it had worked on Knime 4.0 without variable, though.
Could you please help me to run this node without error message.

Kind regards.


The error message you receive most likely caused if the SCHRODINGER environment variable is not set before starting Knime.
You can do this in the command line or you can use the File > Preferences > Knime > Schrodinger menu option and set the SCHRODINGER installation location here.
You can find more information regarding this from the following link from our website:

I hope this helps, but if the problem still remains, please contact us directly by writing to and we would be happy to help further.

Many thanks,
