Hi, The tasks are triggered by the scanner (so you can assume the start of the acquisition is at t=0) and you can assume that the spacing between frames is exactly the TR (0.720 sec for the 3T HCP-Young Adult acquisitions).

I would like to match the experimental stimulus (for which I have exact time stamps) to the fMRI images. However, so far I could only find out that there are 284 frames per run and that the run lasts 214 seconds, which gives me an approximate timestamp if I assume they are perfectly evenly spaced and the first measurement is at exactly t=0. Is there any way to get the exact time for each fMRI image? Thanks in advance and greetings from Munich, Katy _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users ________________________________ The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.
