Some issues about scrubbing

Dear Chao-Gan,

I used scrubbing method to reduce the effects of head motion following reviewer's suggestion, but I have some questions about it, as follows:

1. Does this method directly delete 'bad' time points?

2. Is there any file containing the information about the remaining time points for each subjects after scrubbing? I would like to easily check which subject to be excluded.

3. The default FD used in the DPABI is 0.5, but it is 0.2 in Power et al. (2012). I have tried FD<0.2, but a great number of participants have to be excluded due to this criterion. I was wondering if FD<0.2 is too stringent and could I try more liberal criterion such as FD < 0.5 or something else?

4. I have analyzed both ALFF and rsFC measures. Since the scrubbing was done at last when preprocessing, is it meaning the ALFF data were not scrubbed?

5. I do not like scrubbing because it led to a great loss of data (both time points and participants). I have excluded participants whose head motions exceeded 3mm or 3 degree, and used friston 24 model to further reduce the impact of head motion for remaining participants. Is it possible to persure the reviewer that I have already done enough to reduce the covariates of head motion.

Thank you in advance!
