KNIME: Extensions Downloads

KNIME allows to easily integrate new modules, i.e. analysis nodes. Available below are some node extensions for use in the KNIME product or the KNIME developer edition. These extensions are not part of the base KNIME download. Some of them depend on third party implementations and are distributed under a different license. The license file is available in each of the archives, make sure to carefully read it before using these plugins.

The installation of plugins is straightforward. For the standard extensions you can use the KNIME Update mechanism as described in the Update Site Help. But you can, of course, also download the archive manually, unzip it to your KNIME installation directory, and restart KNIME.

• KNIME R Feature:

  This feature provides an interface to the R statistical software (http://www.r-project.org). In order to run this feature, you additionally need to locally install R from the project website or the R Server, in order to connect to a remote R instance.
  • R-project feature for KNIME 1.3.5 (0.2MB)

• KNIME Chemistry Extension:

  Available are two actual chemistry extensions, both of which depend on a chemistry types feature, defining new molecular data types (but no new nodes):

  • Types chemistry feature. This feature is mandatory for both feature, the basic chemistry tools feature and the CDK feature to function properly.

    • Chemistry types feature (0.1MB)

  • Basic chemistry tools containing MoSS, the Molecular Substructure Search node, to find frequent fragments in a set of molecules, and OpenBabel to convert various molecular types.

    • Chemistry tools for KNIME 1.3.5 (0.6MB)

  • The CDK feature is the second chemistry feature. It is based on the Chemistry Development Kit (CDK), available at http://cdk.sf.net.

    • CDK Chemistry feature for KNIME 1.3.5 (9.5MB)

• KNIME Data Mining (Weka) Feature:

  This feature provides an interface to the well known Weka data mining environment. (http://www.cs.waikato.ac.nz/ml/weka/). In order to use the Weka-functionality within KNIME simply download and install this feature:
  • Data Mining (Weka) feature for KNIME 1.3.5 (8.6MB)

• KNIME JFreeChart Feature:

  This feature integrates JFreeChart into KNIME such that the rich chart-functionality of JFreeChart can be used in several additional nodes (Pie Chart, Bar Chart, etc.).

  • JFreeChart feature for KNIME 1.3.5 (6.6MB)

• KNIME Mathematical Formula Plugin for KNIME 1.3.5

  This plugin contains a single node called "Math Formula", which allows you to evaluate free-form mathematical expressions. The result is appended as a new column to the input table. The functionality is like the one of the Java-snippet node (which is part of the KNIME base package) but without the requirement of knowing the Java language.

  This node uses code from JEP 2.4.1, a Java library for parsing and evaluating mathematical expressions, which is released under the terms of the GNU GENERAL PUBLIC LICENSE (GPL). The source code of the used library is available here for download.

  To install the plugin, download the following package and extract it to your KNIME installation directory.

  • KNIME Mathematical Formula Plugin for KNIME 1.3.5 (0.4MB)

• KNIME XLS Writer Plugin

  This node writes out the datatable into a spreadsheet of a workbook. The files can be read then with other applications like Microsoft Excel, for example. This plugin makes use of libraries from the Jakarta POI project which is part of and copyrighted by the Apache Software Foundation.

  To install the plugin, download the following package and extract it to your KNIME installation directory.

  • KNIME XLS Writer Plugin for KNIME 1.3.5 (1MB)

Experimental Extensions

(Download archive and unzip into your KNIME installation directory.)

• KNIME External Tool Plugin for KNIME 1.3.5

  Allows running an external program on the data. NOTE: Running an external executable takes the control out of KNIME's hands. This node may crash or hang KNIME and you risk loosing any unsaved data. There will be no progress, no cancel option, in case of failure processes may be dangling in your system, etc. Highlighting will not work across this node. Colors are lost. Use this node at your own risk.

  To install the plugin, download the following package and extract it to your KNIME installation directory.

  • KNIME External Tool Plugin for KNIME 1.3.5 (0.1MB)

• KNIME Reporting (BIRT) Feature:

  This feature provides two nodes to generate tabular reports of your data. Even image data or rendered molecules can be integrated. The reports can be saved as .pdf or .html files. In order to run this feature this archive contains parts of the Eclipse BIRT feature (http://www.eclipse.org/birt/phoenix/).

  • Reporting (BIRT) feature for KNIME 1.3.5 (22MB)

• KNIME Neighborgram Plugin

  A neighborgram is a one-dimensional model of the neighborhood of a chosen pattern, which is called the centroid. Other patterns are mapped into the neighborgram depending on their distance to this centroid. Essentially, a neighborgram summarizes the neighborhood of the centroid through a ray onto which the closest neighbors of the centroid are plotted. For further information refer to the publication:
  Michael R. Berthold, Bernd Wiswedel, David E. Patterson, Interactive Exploration of Fuzzy Clusters Using Neighborgrams , Fuzzy Sets and Systems, vol. 149, no. 1, pp. 21-37, Elsevier, 2005 PDF

  In order to use the neighborgram visualizations in KNIME you need to download and install this plugin in your KNIME installation directory.

  • Neighborgram plugin 0.9.1 for KNIME 1.3.5(0.2MB)
