Dividing data set into training and test data sets

[nsprt]

Hello,

I have a data set contains 240 trials. I need to use 20 for training and 20 for test. Which box can do that. I tried to use the first 20 trials using keyboard stimulator for training but I can't use the trials from 10-30th. Also, how can I do that for test.

Thanks

Hello nsprt,

how is your data set structured? How are the trials tagged? Depending on the stream structure you can either use Stimulation Based Epoching or Time Based Epoching to extract the data you need.

Thank u Jozef for your response

I'm working on data iib(two classes) from BCI competition. How can i do that using Stimulation Based Epoching. I think Stimulation Based Epoching allows for the signal after completing the time specified in settings? is that true? and how can i do it using time based epoching.



Best regards
