Dear SPM users,
If an experiment has two types of stimuli (A and B) and, for each type, the subjects can answer True or False, (then we have
four conditions:
1. ATrue
2. AFalse
3. BTrue
4. BFalse
If a subject always answers false to the stimuli of type A, then we have no onsets and no durations for the condition "ATrue".
What must be entered as onsets and durations for a condition without events?
When I write nothing for a condition in the MultipleConditions.mat file, the analysis doesn't work.
You're help would be really appreciated.
Regards,
Steve
