Hey,
I have removed the first 5 volumes, have applied slice time correction, and have processed the data with Pestica/Slomoco (version 5) to correct for physiological cardiac and respiratory noise and motion. I have also normalized the data to MNI152 using FSL's flirt and fnirt. For ALFF calculation in AFNI, I have not used the -nodetrend flag but I will definitely try that, thank you!
In DPABI, I have used the GUI of DPARSF 5.3 Advanced Edition. I have selected a blank template, loaded the same input as descriped above and have only selected "ALFF/fALFF Band (Hz): 0.01 ~ 0.08".
Best, Melissa
