Dear AFNI experts,

I am wonder what is the difference between these two examples of censor motion using 1d_too.py.
What is different when you use '-censor_motion' or '-moderate_mask'? 

       a. general example ~3~

          1d_tool.py -infile motion.1D -set_nruns 9     \
                     -derivative -censor_prev_TR        \
                     -collapse_cols euclidean_norm      \
                     -moderate_mask -1.2 1.2            \
                     -show_censor_count                 \
                     -write_censor subjA_censor.1D      \
                     -write_CENSORTR subjA_CENSORTR.txt

       b. using -censor_motion ~3~

          The -censor_motion option is available, which implies '-derivative',
          '-collapse_cols euclidean_norm', 'moderate_mask -LIMIT LIMIT', and the
          prefix for '-write_censor' and '-write_CENSORTR' output files.  This
          option will also result in subjA_enorm.1D being written, which is the
          euclidean norm of the derivative, before the extreme mask is applied.

          1d_tool.py -infile motion.1D -set_nruns 9     \
                     -show_censor_count                 \
                     -censor_motion 1.2 subjA           \
                     -censor_prev_TR

Best regards,
Karel
