[Eeglablist] ICA training at 0.1Hz- can it be done?

[Ahmad, Jumana]

Hi all,
I ran ICA with either a 0.1Hz or 1Hz filter. 0.1 does not give stable components- multiple blinks, and fuzzy looking brain maps.

However, I wanted to avoid transferring the weights from 1Hz to 0.1, incase the 0.1Hz, which does not get fully characterised within the training, subsequently gets removed when we exclude eye blinks etc. Although this is fairly unlikely, I did wonder if there would be an alternative to help my decomposition at 0.1Hz?  Something that would also not distort the ERP.

I wondered about de-trending, but again, I am unsure how this would distort the ERP and I am not sure if this has been tested?

Best wishes,
Jumana
