You'll see that In the raw data, neighboring channels "EEG 015" and "EEG 016" have a correlation coefficient of .90.
According the pipeline's correlation calculation, both channels have an average max correlation of about .30
When even highly correlated channels come out with low correlations, it makes them group together with actual uncorrelated channels, making the bar for flagging any channel as low_r difficult.
