KNIME Workflow

kota's picture

KNIME allows you to interactively compose workflow using GUI. The workflow you created can be saved as a zip file and imported later to redo the analysis.

Inside the workflow zip file is multiple folders called "Nodes", each containing parameter settings for components (functions, or image processing algorithm implementations). In a sense, KNIME workflow is a structured set of XML files that specifies the processing parameters and the order of processing.
