Hi mb,

BLOCK(6,1) should be different than BLOCK(3,1),
though there might not be a huge statistical
different in the results. To see the difference
in the regressors, event at a 3s TR, try:

3dDeconvolve -polort -1 -nodata 10 3 -num_stimts 2 \
   -stim_times 1 '1D: 0' BLOCK'(3,1)'              \
   -stim_times 2 '1D: 0' 'BLOCK(6,1)'              \
   -x1D x.xmat.1D -x1D_stop

1dplot -one x.xmat.1D

The results should not be identical, but similar.
