Hi Gang,
In the 3dDeconvolve help files,
==> ** Despite the name, you can use 'BLOCK' for event-
related analyses just by setting the duration to
a small value; e.g., 'BLOCK5(1,1)'.
Therefore, I am not sure which ‘BLOCK’ (BLOCK(1,1) or BLOCK5(1,1)) is more suitable in my experiment.
Thank you very much.
