Hi,

Thanks for reply.

Briefly, I try to compute ReHo,ALFF and fALFF from the resting-state fMRI data. According to your reply, I will not use bandpass filter - 0.01 0.1 Hz- in afni_proc.py. After the processing I will compute via 3dLomb and 3dAmp. By the way, I do not have any good reason to use bandpass filter , I use it because it is in default parameters for all the other AFNI like tools *and I used them for same data CONN, SPM, DPARSFA *. Computing process without bandpassing, will it cause any problem at ReHo analysis ? Moreover, if data has many useful information above 0.1 Hz should I use ALFF band of 0.01-0.2 at 3dAmp 3dLomb (According to paper) or should I leave empty ?

Is the censoring time point about movement ? If it is so, I have only the output file named "X.nocensor.xmat.1D" should I enter this ?

Yes I found QC at previous process it says "degree of freedom used=16 " and "degree of freedom left=132" for the analysis performed with -banpassed 0.1 0.01 and regress_RSFC at afni_proc.py

Thanks
Abdullah
