New version with XDF file support

This is latest multi stream file but no Open?BCI yet (will create one today)

The view by pyxdf:

strong text

The use case of multiple streams (in my case at least) would be seeing selected channels (including non=EEG channels - wiimote and pylsl) so the users can focus their analysis for example on fragment between 2 wiimote markers or after a particular pylsl marker.
I do not see a use for the wiimote sensor data channel yet and am not sure how they could be presented in =Brainstorm GUI so at this stage I am ok for them to be ignored.

Please let me know when/how I can help any further here.

Peter
