P300 Speller doesn't start

[bertocasta]

Hello,

I've been trying to do a P300 Speller with my Enobio system usign BCI2000.
After set the config and start the Speller, a screen appears telling it is been started but then, nothing more happens.

Screenshot:


It isn't flashing the letter and numbers.

Any help?

One of the warnings says "the actual value of StimulusDuration for stimulus 1 will be 0 ms". You have to increase your stimulus duration parameter or decrease your sample block size.
