+Not pictured: you can now check the "Save Preprocessed Copy" under the "Run" button to save a filtered, whitened, and drift-corrected copy of the data to "temp_wh.dat" in the results directory. This will also reformat the results for Phy so that the preprocessed copy is used instead of the raw binary file.
+
 If you run into errors or the results look strange, you may need to tweak some of the other settings. A handful are shown below 'number of channels' and 'sampling frequency,' or you can click "Extra settings" to open a new window with more options. Mousing over the name of a setting for about half a second will show a description of what the setting does, along with information about which values are allowed. For more detailed suggestions, see :ref:`parameters`
