number of channels reduced even after interpolation #52

Closed kkauraiims closed 2 years ago

kkauraiims commented 2 years ago

Hello, I have run Automagic on 128 channel data (EGI), however, even after using the 'interpolate all' option my output channels are still very low (118/128). I need all the channels for further downstream analysis, can someone help with this?

I have attached a sample log file for reference.

Hi,

I see from the txt file that you used EOG regression. Did you regressed out 10 EOG channels? If yes, that is the reason why they are missing. If you need those channels for further analysis, maybe try to skip EOG regression and let the ICA correct for eye movements.

Best, Dawid

Thanks! It worked, I have all 129 channels.

On the downside, if I go by the quality rating, I now have more files marked as 'Bad'. Seems like EOG Regression is very useful provided we circumvent the issue of missing channels!
