AFNI and ICA?

AFNI Message Board

Hello!

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:
https://afni.nimh.nih.gov/ICA

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.

Thanks!

3dICA.R is just a simple tool for spatial ICA as shown on the web page you linked. Unfortunately there has been no further development.

Thanks Gang!
So there is no equivalence in AFNI to the ICA tools in Conn for example?
