It depends exactly how you triggered your paradigm. If you used the scanner to trigger the start of your stimulation, then you do not include the 6 sec when preparing your paradigm files.

Hello,

My name is David Brohawn, and I am one of Dr. Roffman's research assistants.

We run the SIRP and N-Back memory tests with our subjects.

We have specified for 3 dummy scans to take place at the beginning of each of these protocols, which takes 6 seconds of scanning time, respectively.

When writing paradigm files in freesurfer, should we include a 6 second period to account for these dummy scans, or do we write the paradigm files not making any reference to the time elapsed during these dummy scans?

Thanks,
