Important Notes

The calculation parameters in the example workflows have been chosen so as to minimize the calculation time, not to produce scientifically valid results.

The workflows have been executed and saved with the intermediate data. You can reset all the nodes in a particular workflow except for the first node, if you wish to execute the workflow using the example data. You only need to download the example input data if you want to execute the whole workflow from scratch.

Include optional example data in the download.

Installation Instructions

After you have downloaded Schrodinger_Workflows_Download.zip, you can import the workflows by following these steps:

  • In the KNIME Workbench, choose File->Import KNIME Workflow...
  • In the Import panel, click "Select archive file" and then Browse...
  • Browse to and select the Schrodinger_Workflows_Download.zip file
  • Click Finish

To install workflow example data (if included in the download):

  • On Linux
    • Move the Schrodinger_Workflows_Download.zip file into an empty directory and unzip the file:

      unzip Schrodinger_Workflows_Download.zip

    • Move the knime_workflow_example_data.zip file into /tmp and extract it:

      mv knime_workflow_example_data.zip /tmp/
      cd /tmp/
      unzip knime_workflow_example_data.zip
  • On Windows:
    • Move the Schrodinger_Workflows_Download.zip file into an empty directory and unzip the file.
    • Choose a directory in which to unzip knime_workflow_example_data.zip.
    • The example workflows provided in the Schrodinger_Workflows_Download.zip were saved under Linux, and are configured to use example data in subdirectories under /tmp/knime_workflow_example_data/. Since there is no /tmp/knime_workflow_example_data/ directory under Windows, you will need to reconfigure the nodes in the workflows to point to the location where you have unzipped the knime_workflow_example_data.zip file.
