MatlabSnippet-Node extension for KNIME Workbench version 4.0.0.v202006300844 by Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG)
This node executes a snippet/script using a local Matlab desktop instance to produce a plot (graph). The Matlab script can be coded manually or templates can be selected from a snippet template repository. Templates can be used as such or they can be modified to the users liking.
RGG (R GUI Generator) is used to configure the Matlab code using a graphical user interface in a way that the user does not need to know scripting in Matlab.
Copy, cut or paste and Matlab code to the editor and/or select the columns from your data table. If a template is loaded used the GUI to adapt the script to the input data.
Select a plot template from the template repository (double-click or "Use this template") to use that script and see the GUI. The description shows you an example plot than can be done using this template. Then configure the GUI according to your input data.
Specify the image dimensions of the plot and the type and location where to save that image.
This node needs a Matlab installation on the local machine!
If Matlab is not running, the node launches an instance of the Matlab desktop. It is recommended to let KNIME launch Matlab. The node can detect open Matlab instances, but this is not foolproof.
