Re: Is there a way to change the Graz Visualisation blue feedback bar to be vertical?

Hi Thibaut, thank you for your reply. I have changed to the multimodal graz box and it seems to be more what I am looking for, however, the feedback display is much worse. With the Graz visualisation box the visible blue feedback bar was usually pretty large. With the multimodal box I can't seem to ...

Re: Where has the box window gone in openvibe 3.0?

Never mind, I found it, it was just squished all the way to the edge of the screen, making it invisible.

Where has the box window gone in openvibe 3.0?

I recently downloaded the newest version of OpenVibe. On previous versions the designer came with a section on the right hand side where you could search for boxes. This does not seem to be visible in the newest version of OpenVibe. Does anyone know how I find and add boxes to a scenario in the newe...

Is there a way to change the Graz Visualisation blue feedback bar to be vertical?

We are using the CSP scenario, but would like the blue feedback bar in the online scenario to be vertical instead of horizontal. Is there any way to do this?

Does anyone know why my classifier score is so high in the CSP scenario?

I have ran this scenario a few times and when training the classifier it seems to always be around 98-99%. We are doing 30 trials for the training data. This score seems way too high though, I was expecting something closer to 70-80%. Would 99% really be correct?

When running the CSP filter trainer scenario we get the following errors: [ WARNING ] Box <CSP Spatial Filter Trainer> sends inconsistent chunk dates on output [0] (current chunk dates are [1258224091136,1258291200...

Is there a way to measure the score in the spaceship example?

I am trying to use the spaceship example for neurofeedback, and was wondering if there was any way to get an overall "score" at the end, some sort of measurement of how much the spaceship moved overall, as we are trying to measure a rate of learning for neurofeedback. Is there some way to do this?
