I think that #1 should work (#2 should work too, but it is less preferable).

Hi Doug,

thanks alot! But see, I did it again, asking either or questions, and being totally stomed to get a yes as response :). So do you think

1. specifying two ID codes at the same onset time will work?

or

2. staggering the onset times of both ID codes around the true onset time with a high TER would work?

or both?

I will just go and try both, I guess :)

Thank you very much for your help

Best Sebastian

Dear fellow Surfers,

is it possible to model several independent event streams for fs-fast? That is, using the 5 column paradigm file, is it okay to have different condition ID codes that have identical stimulus onset time (well only some of the time)? Or would I have to model that by specifying a TER and have both staggered around the real onset time? I would be happy to receive any pointer.

Thanks in advance & best regards Sebastian
