I am a new comer to fMRI/NeuroScience, so my apologies if this question is too basic.
I understand that repetition time(TR) is the time between successive RF pulses, for measuring the fMRI signal.Also there are TrialOnSet Times, at which we show the subject some stimulus.
Can someone suggest about:
how TrialOnSet Times and repetition time(TR) are related. For example for the dataset dataset, Trail onsets starts from 6+ second and their repetition time is 2 s. Does that mean we record first fMRI Image/volume at 0s, or at 2 s.
