[Eeglablist] BCI P300 Speller

[Yalda Shahriari]

Hi EEG Lab members. I'm studying M.S in Iran university of science &
technology. I'm working on BCI P300 speller and I have a question with
it's timing. the columns and rows intensify for 100 ms in random and
for 25 ms all of them are off and then another randomly columns or
rows (c/r) intensifyes. and I know that P300 appear around 300 ms. so
how can I record each epoch seperatly?
