Hello Gaurav,

You'll have to look into the matter yourself since ringing depends on your data and the method with which you perform the filtering. Our recommendation is in the implementation in afni_proc.py which is based on the algorithms detailed in Jo et al 2013. Ringing should not be a matter of concern since we usually bandpass and censor the data in a linear regression framework.

cheers
