5.2.4: Open Brain Wave Data Only
After Run IBVA4, setup this window to make on "Open Brain wave data only".
Then open a "Brain Note" file. Open Brain wave data only. No preferences are effective.
5.2.5: Open Preferences Only, Except Device USB PortSetup, MIDI Port Setup and Recording, Max Time
After Run IBVA4, setup this window to turn on "Open preferences only". Then Open a Brain Note file, to open preferences only, except Device USB port setup, MIDI port setup and Recording, Max time. No Brain wave data in the data buffer is effective.
5.2.6: Save Brain Wave Data Only
Save "Brain Note" file creates a file only containing brain wave data. No preferences are saved.
5.2.7: Save Preferences
After Run IBVA4, setup this window to turn on "Open preferences only".
Save "Brain Note" file makes a preference file only. No Brain wave data will be saved.
This keeps file sizes small.
* If you changethe USB connection setup or run it on another Mac, then DO NOT TURN ON "Device USB port setup".
* Time taken to open a 1-hour and 2 channel Brain Note file is about 15 to 30 seconds, depending on speed of your Mac.
* 1 hour 2 channel brain data file is about 12 MB. File save time is 60 second.
