Problem generating .cfg in Speller train classifier

Post by tonio112003 »

Hi!

I don´t know why but, when the Train Classifier ends, doesn´t generates the .cfg data

Can anyone help me please?

I have this scenario

I am expecting something like this in the classifier part but it doesn´t happen

Hi Tonio,
I think that the trainer is not getting the Trigger for stimulation. Try using the keyboard stimulator, and don't forget to change the Train Trigger Stimulation to that of the Keyboard. I hope that it will work.
Thanks.

uahmed you were right, thank you very much.

The Lua script had a problem and did not sent the train trigger.
I fixed and now works fine,

thanks
