[Freesurfer] abblocked Setup

Hello,

We are trying to set up the analysis for a periodic design alternating between 30s rest and 30s active condition. Because abblocked doesn't require a paradigm file, how do we specify which condition comes first (rest or active)? We understand that abblocked expects that the conditions will be alternating.

Also, how do we set up the -a and -c weighting conditions if we are using abblocked, since it doesn't have a paradigm file? How do we specify the arguments for this command? Should we instead be using the -ncond and -wcond commands?

Best,
