[Eeglablist] Inquiry about clean_artifacts.m function

[Velu Prabhakar Kumaravel]

I think it is the RANSAC algorithm that produces inconsistent removals. You
might take a look at Makoto's page here
<https://sccn.ucsd.edu/wiki/Makoto's_preprocessing_pipeline#Channel_rejection_using_RANSAC_in_clean_rawdata.28.29_.2803.2F21.2F2022_added.29>
.
