Oh, then you probably want to use 3dSynthesize. But in order to use it, the prior 3dDeconvolve command would need the -cbucket option included.
Add "-regress_make_cbucket yes" to the afni_proc.py command. It would then include an appropriate -cbucket option in 3dDeconvolve. So after the proc script is finished running, you would be able to use 3dSynthesize to extract whatever you want.
Pleas see
3dSynthesize -help for details.
