raw data written to file?

in OpenBCI_GUI
I want to verify what data gets written to file in the OpenBCI GUI. The live display suggest implies a windowed RMS value - is that what gets written to the file? In the top left (if time series is selected among hardware settings options) there is the option of a band pass and notch filter... if these are active is the saved data processed? If these are not selected the live display still suggests a windowed RMS value... so I'm a bit confused. thanks.
I'm recording sEMG at 1000Hz using Cyton and wifi shield.

    The recorded file is raw data, with no filtering, regardless of GUI button settings. GUI displays show filtered data based on the button selections.

    How to process the raw data, and make the raw data as same as the GUI display?

    The GUI has buttons that apply various filters, such as bandpass, notch, etc. If you apply similar filters to the data stream, you will see similar results. A typical setup might apply a bandpass from say .5 Hz to 45 Hz. Then a notch at your mains frequency.
