P300 Speller, Problem with Online Part

[tonio112003]

Hi!

I have recorded and classified a training with 16 letter using 6 channels.
Now, I have this scenario to work with the Online part of the speller and shows this message:

[WARNING] <Algorithm::LDA classifier - GPL> Feature vector size 384 and hyperplane parameter size 307 does not match
[WARNING] At time 7.766 sec <Box algorithm::Voting Classifier> Input matrix should have a single value
[WARNING] Box algorithm <Voting Classifier> has been deactivated because process phase returned bad status

Can anyone help me please?

Did you change anything to the scenarios? It seems you get different number of features when doing the online experiment (compared to the training data), maybe you changed the epoch length, the decimation factor or you have a different number of channels that are coming from the acquisition client?
