Sorry for the inconvenience! I know I asked many questions in the past, but now I have a very bad problem with the new version 3.0.0 (December 2020) ! I would work with the new version also because I would use the Artefact detection.
The problem: the problem is the same working with P300 Speller or working with P300 Speller XDAWN.
PC, Win 7. In the “ONLINE” the selected characters are not showed. To get a good documentation for you, I run a test with your 2 test-datasets (date 2016-04-20). I used the first one for the training Xdawn and for the training classifier. I used the second one in the Replay. Also with your datasets I don’t see any result, I don’t’see any character selected!!!
I attach the print screen where it is possible to see what I am saying. And I attach also the print-screen with 4 Warning message.
With version 2.2.0, it is OK! The scenario works well and I see the selected characters!
Thank you!

Hi,
It's exactly the same scenario and dataset in input ? If yes, it's certainly a bug in new version. A lot of improvment were done and can break some stuff.

Thank you!
They are the same scenarios (P300 speller and P300 speller Xdawn) with the same your datasets in input (training and online dataset, both with date 2016-04-20).
When you'll give a look, if I can help you, I can give to you other infomations about my tests to understand the problem.
