[Eeglablist] Highly Correlated channels after applying ASR

[Vishal Vijayakumar]

Hello,

Apologies if you've answered this question already, but I observe that data
across my channels look highly correlated after applying ASR to the
filtered EEG data. My project involves analyzing tonic thermal pain, so I
apply ASR to 4 minute segments of the data. Because of the high
correlation, my ICA sphering matrix is quite large in magnitude (minimum
value of 1800) for many subjects. I also disable any channel-based
rejection because I'd like to concatenate data across subjects for group
ICA. My current problem persists even during single subject analysis.


I'm not sure if I'm doing something wrong, and I'd appreciate any insight
you can provide!

Thanks,
Vishal
