In a comprehensive study we defined 10 events, where subjective ratings in
categories were linked to fMRI data.
These 10 events are defined by 3-column textfiles. However: some subjects
have one of the 10 events missing, for example because they didn't use one
of the possible ratingcategories.
Is there a possibility of defining an event as a MISSING VALUE ?
It would greatly help to leave all the contrasts I defined as they are and
not having to define for each individual a new design,(and will make it a
lot easier with the Higher-level analysis later.)
thanks,
