Hi AFNI friends,

What is conventional wisdom regarding masking (or not)?

I have 4 modeled regressors. In a single trial, M occurs before 1, 2, or 3.

M is the result of a generic somatosensory/motor process. Responses to 1, 2, or 3 include the aforementioned generic somatosensory/motor process, but also include additional, distinct, sensory responses.

Think of reaching (M), versus reaching and acquiring (M+1, 2, or 3).

Can I mask the response to 1, 2, or 3 with mask M?
