Re: Mu Rhythm Linear Classifier Signal Questions

Thank you very much for the reply. I realize now that the correct weighting is [-1 1 -1 1]. This would apply negative weighting to the Mu and Beta bins from C3 (Right hand movement) and positive weighting to the Mu and Beta bins from C4 (Left hand movement).

Mu Rhythm Linear Classifier Signal Questions

Hello I have some questions regarding the mu rhythm linear classifier and ensure that we are using the correct control signals. For spatial filtering we simply use the CAR filter type. From this, we select C3 and C4 as outputs of the filter in the "SpatialFilterCAROutput" box. My question is in rega...

Newbie Question EEG Marking

Hello, I am relatively inexperienced as far as programming goes. I was not part of the team that set up the current iteration of BCI2000 that we are running but I would like to add an event marker to the EEG that can be used in EEGLAB to better evaluate the EEG. We use the StimulusPresentation modul...

Re: RoundTrip Data

Hi Jürgen,

I would greatly appreciate assistance on how to set that up. Sounds relatively straightforward but I have limited experience in C++ help would be welcome so that I don't spin my wheels unnecessarily.

Thank you,
Erik

RoundTrip Data

Hello,

Is there a way to extract RoundTrip data from existing data? Or is this only possible through running BCI2000 with SignalGenerator and FilePlayback?

Thank you.

Update: I deleted the Operator.ini file and everything seems to be working as normal.

Adding Dig I/O channel to channel list.

Hello, We are attempting to make use of the Dig I/O on the g.USBamp to add marks to the EEG for when a stimulus is applied. I've figured out the enable digital input option in config>source>DigitalInput and am able to see the "tick" marks in bottom trace of the EEG. I've attached a picture of what t...
