Dear Booer,

ICA can be severely compromised by 'bad data'. Use very aggressive cleaning
& filtering, obtain ICA matrix, and apply it back to the moderately cleaned
& filtered data may work.

Use clean_rawdata() and use ASR threshold 20, which produced the best
results out of 19 other methods we compared (unpublished!) Check the EEGLAB
plugin manager or download it from
