Silly question, but I have never used ICA for neither cleaning/de-noising or for analysis.
A post here from 2016 stated that AFNI did not have any ICA tools. But I did find that it now does:
This seems to be the AFNI version of doingICA de-noising. I.e. using ICA for pre-processing.
Does AFNI now have ICA for both pre-processing AND for analysis?
The sillyness of this question might be that I lack the understanding of the difference between anaysis (getting results) from ICA and using ICA for pre-processing /cleaning the data and group-ICA.
