[Eeglablist] ICA decomposition filtering and subsampling

[Marco Bellami]

Hi everyone,



I'm a new EEGLab user and I have a (probably trivial) question about ICA
decomposition. I have a dataset with a sampling frequency of 2048 Hz. Then,
for my analysis I filtered EEG data considering only the [0.1 60] Hz band. I
read that it is better to use in the ICA decomposition as many points as
possible but conidering the filters that I used and the sampling theorem a
120 Hz sampling frequency should be enough. After filtering, should I keep
the original sampling frequency to improve the component detection or is it
possible a sub-sampling?



Thanks so much



Greetings.

Marco
