PMM-Lab Installation

In this Section we will go through the steps of installing PMM-Lab.

+ Visit
+ Download the KNIME distribution that fits to your Operating System.
+ Locate the downloaded KNIME self-extracting archive file and execute it. You will be asked to specify a location where, on your hard disk, you wish to install KNIME.
+ Go to the specified KNIME directory and run the executable file called ‘knime.exe’ in the case of Windows users or plain ‘knime’ if you are a user of Linux or Mac OS X.
+ Note that KNIME doesn not include a JRE for the Mac. Therefore, Java needs to be installed on the machine. For PMM-Lab Java7 is needed!

You accomplished installing an instance of KNIME and eventually adding the PMM-Lab plugin. You can now use the PMM-Lab nodes in the Node Repository to perform specific calculations in the field of predictive microbiology.

  • Choose from the main menu
    • ‘Help’
    • ’Check for Updates.’
