Hello all, I'm using a Motor Imagery scenario with openvibe. Is there a way to get Sensitivity-Recall, Specificity, and Precision from the software? If not how can I compute it? From the cross-validation confusion matrix in the image below: https://i.ibb.co/SQMX58j/MI-CSP-Sofia-imagery-16ch.png TP =...

Dear Thomas,

Have you found out what is happening in my case?

Dear Thomas, Thanks for the quick response. Please, find the files in the following link: https://drive.google.com/file/d/1zGH1NhMb7WgHNfXymuYoVRG3QB7C7n_2/view?usp=sharing mi-csp-1-acquisition.xml is the scenario used to record EEG Data. mi-csp-2-train-CSP.xml is the scenario used for CSP mi-csp-3-...

I am trying to understand how the "Time based epoching Box" works. I use the classic MI-CSP Left vs. Right with Default parameters. Number of trials in each class = 20 Device Sampling Frequency 125 Hz Stimulation Based epoching epoch duration = 4 sec epoch offset = 0.5 sec Time Based epoching epoch ...

Hello mhadji05,

Have you found a solution for this?

It is very interesting and useful if we can use so many algorithms in our scenarios.
If you manage to use Sklearn, please let us know how it is possible.

Hello,

What are the differences between .ov and .gdf file and why?
Is it better to save my EEG signals in .ov format or .gdf format?
Are there other options except of these?

Dear @FabioBCI,

Have you succeed to run the Random Forest classification algorithm with PyBox in Openvibe?
