[Eeglablist] ICA filtering and IC semi automatic classification

[Alexandre Obert]

Hi all,

I read somewhere
<https://github.com/CSC-UW/csc-eeg-tools/wiki/Filtering-and-ICA>that one
could perform ICA onto data filtered with 1Hz (high-pass) and then apply
ICA matrix onto 0.1Hz filtered data.
However, I wonder how to deal with ICs classification algorithms such as
SASICA or ADJUST in such process?

SASICA onto 1Hz filtered data send different results from SASICA onto 0.1Hz
filtered one.
So, what's the best process:
1) performing SASICA onto 1Hz data and then reject artifactual ICs in 0.1Hz
(don't feel comfortable with this)
2) forgetting such process and just using ICA and SASICA onto 0.1Hz data
directly
3) following the mentioned process and performing SASICA onto 0.1Hz data
with ICA matrix from 1Hz data
4) something else
