Train CSP On Multiple Files

[amemov]

Hello,

I'm using OpenViBE's scenario for motor imagery, and I was wondering if it is possible to combine multiple files into one for training CSP or to train CSP on multiple training files. I saw that OpenViBE uses for training files with extension .ov, and because of that, I'm not sure how should I approach this problem.

Hello.
Have you tried the "Signal Concatenation" box?
According to its documentation, it seems to be suitable for your case.

kyunghowon,

Thank you. Yes, I just tried it. It works perfectly fine with concatenating just 2 training files, but when I attempt to train on multiple files as seen below, it crashes almost immediately. I'm not sure what exactly is wrong. I tried searching the forum to see if someone encountered a similar issue, but I haven't found any posts.
