Dear Thibaut,
after a lot of tests, I succeeded!!!
Thank you very much for the scenario that you built to get this other option to concatenate 2 files!

Re: Classifier: Incremental Learning
Dear Thibaut,
I put on Filter Box the parametr that you can see in the attached image. The filter box is only for the first file.
Now, the train classifier worked only for the second part of the concatened file... .
Where am I wrong?
Thank you
Ettore

Re: Classifier: Incremental Learning
Dear Thibaut, I would say to you: THANK YOU!!! Now, I didnt'understand what I have to do when you wrote "You must just remove the stimulation who run the train on all scenario except the last". And I tested the new little scenario, but I didn't remove anything. I only wrote, in your new scenario, th...

Classifier: Incremental Learning
Before to ask my question, congratulation for the new versione 3.0.0!!! I have a question to try to train better the classifier. I think that the argument is known as “incremental learning". Now: -I am on Openvibe 2.2.0 -I run the scenario P300-speller-1-acquisition; the Generic-stream-writer writes...

Re: Epoch duration
Thank you very much Thibaut for your answer! Sorry for the delay of my new answer: I had the fever! You remember very well! I am tryng to work with the P300 Speller scenario. The question is: if (for i.e.): 1) in the box "P300 stimulator" (in the P300 Speller acquisition) I indicate a flash duration...

Epoch duration
Sorry for my bad English! In this example: Flash duration: 0.1 No flash duration: 0.5 Epoch duration: 1.2 sec., I think that a target-epoch (i.e. with the start from the stimulation target), will get the EEGs for one target stimulation and also for one no-target stimolation. Is this a problem for th...

Re: jaw clenching, artifact removal in P300 scenario.
Dear Thibaut, sorry for my bad English! I read your suggestion for me " if you build OpenViBE from source, you can use the box artefact detection with 70 to 100 as parameter" and I installed another Opnevibe from source! The job was very hard...! But I installed the product. But now I dont'see the b...

Re: jaw clenching, artifact removal in P300 scenario.
Thank you very much, Thibaut!!!
I think that because my 6-7 questions are related to a lot of boxes and to a lot of terms about P300, it will be more clear to open a new post.
I need some time to try to write in clear English (Sigh!!!) my questions!!!!
Thank you very much!!!

Re: jaw clenching, artifact removal in P300 scenario.
Thank you, Thibaut! Thank you very much! Two other questions: 1) I am an old programmer (very old...) IBM, Cobol, PL/I, etc... . I have no experience with the new programming languages . Now, I am working with P300-Speller from an Openvibe "Stable Windows Installer". If I try to install Opnevibe by ...

jaw clenching, artifact removal in P300 scenario.
Sorry for my bad English! I am trying to use the P300 scenarios (P300 Speller); I undertsood that some artifacts, i.e. the jaw clenching artifacts, can give a lot of problems finding P300. But the good news is, perhaps, that the signal can be cleaned because the signal made by jaw clenching or by ey...
