You don't need to include the 2nd condition (it will be "absorbed" by the constant term)

Subject: [SPM] 1st Level analysis organization!
Dear SPMers,
I was wondering on how to organize my data for a first level analysis.
I have a block design with 729 scans per subject (12 scans per ACTIVATION and 8 scans of REST).
It will be reasonable to put 2 conditions? one for the activation task ( onsets "scans" 1 21 41 61... "duration" 12) and another for the rest condition (onsets 13 33 53... "duration" 8) ????
any help would be appreciated!!!
Best,
Juan.
