Process the input data using an external application. Upon execution the node will write the input table (possibly split into different chunks) to disk, call the external process as given in the command line field and read the generated output into a KNIME table. This table is finally merged with the original input data based upon the row IDs of the input table. The dialog of the node has different tabs that allow the user to change input/output format of the data, the command line and the chunking of the input data.
The different tabs are described below.
