ARFF Writer

This node saves data to a file in ARFF format. In the configuration dialog, specify a valid destination file. When executed, the node writes the data, coming through its input port, into the specified location. At this point in time, it only writes not-sparse ARFF files (i.e. it always writes out all data, even if its value is zero).

Dialog Options

File Chooser
Choose the file to write to.
Overwrite OK
If unchecked, the node refuses to execute when the output file exists (prevent unintentional overwrite).
