Hi Jun,
Note the one line from 3dDeconvolve:
++ Number of time points: 237 (before censor) ; 111 (after)
That shows 126 time points were censored.
Between censoring and band passing, all of the degrees of
freedom are lost. For more details about the cost of
band passing, please see the afni_proc.py -help output
section "
RESTING STATE NOTE" and the "Comment on bandpassing".
