Dear DPARSF users,
I was wondering if DPARSF is converting the fmri signals from arbitary scanner uints into percentage signal change during the processing step. I will appreciate it if you can let me know. Thanks in advance !!

No.
All the resutls will not be affected by the grand mean normalization.
Except ALFF and no standardization (not divided by mean (mALFF), nor z-standardized (zALFF)).
Best,
