ARFF Writer

This node saves data to a file or to a remote location denoted by an URL in ARFF format. In the configuration dialog, specify a valid destination location. 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).
Note that if the destination location is a remote URL not all options are available because in general it's not possible to determine whether the remote location exists. In this case it will always be overwritten.

Options

File Chooser

Enter a valid file name or URL. You can also choose a previously selected location from the drop-down list, or select a local file from the "Browse..." dialog.

Overwrite OK

If unchecked, the node refuses to execute when the output file exists (prevent unintentional overwrite).
