Hello Rafal, notes below....
1. That does not sound unusual, I remember a pause when running cleanline
in the past. I doubt that it is freezing, it's probably just computing. You
may also want to grab newer versions of the function from the PREP toolbox
from mullen/kothe et al.
2. You don't need EOG for ICA, as frontal channels will pick up stereotyped
eye-artifacts anyway. So I would say if you want to use clean_rawdata, drop
EOG channels before running it. Also, just look at your ICA solutions doing
it different ways, you should not see much difference in eye-related

> b) as in a) but interpolating EOG channels prior to ICA.
> b) running clean_rawdata on all channels except EOG channels so that they
