I have a paradigm where there are a number of conditions during which
there can be correct and in-correct answers. I want to separately model
correct and in-correct responses in my design, however in some instances
there may be no in-correct answers. I obviously want to use the same
model with different onsets in batch mode, for all subjects, however
SPM2 does not allow me to have an empty onset vector. Does anyone have
any suggestions on how to implement this.
Thanks in advance,
Gordon
