Dear Freesurfer experts,

I have a mapping paradigm with block design. Each off-block has a jittered length of 12-14s. Each on-block belongs to 1 out of 5 conditions (in this case stimulation sites). When creating the paradigm-file (like here: https://surfer.nmr.mgh.harvard.edu/fswiki/SensMotOddEvenPar) is it necessary to include each off-block as a separate line? Or is it sufficient to include only on-blocks and silently assume all the rest of the sequence to be of kind „NULL event“ coded with 0 (i.e. similar to what FSL does)?

Thank you in advance!

Sincerely, Simon Desch
