RELAX (The Reduction of Electroencephalographic Artifacts)

RELAX is an EEG artifact reduction toolbox. It cleans eye blinks and movements, muscle activity, and all other types of artifacts common in EEG data, and is most appropriate for data recorded at ≥150Hz with ≥32 electrodes.

If you use RELAX in your work, please cite the following manuscripts:

New cleaning technique:

Additionally, we have recently published a pre-print that explains and tests a method to target wICA artifact cleaning to specific artifact periods and frequencies (in contrast to applying cleaning to all periods and frequencies, which risks reducing neural signals as well as artifacts). If the targeted wICA method is used, the following pre-print should be cited:
