Hi Anita,

You certainly do not want to blur after converting to percent signal
change, the blur should come first (unless, you are blurring in only
gray matter, for example).

Note that we do not recommend masking your data either, until group
analysis. Please see the 'MASKING NOTE' section of "afni_proc.py -help"
for details.

It might be worth reviewing how afni_proc.py writes the processing
script, and comparing it to yours.
