Bad segments

• At this point, you should review the entire files, by pages of a few seconds scrolling with the F3 key, to identify all the bad channels and the noisy segments of recordings. Do this with the the EOG channel open at the same time to identify saccades or blinks that were not completely corrected with the SSP projectors. As this is a complicated task that requires some expertise, we have prepared a list of bad segments for these datasets.

• Open Run01. In the Record tab, select File > Add events from file:

  • File name: sample_auditory/data/S01_AEF_20131218_01_notch/events_bad_01.mat

  • File type: Brainstorm (events*.mat)

  • It adds 12 bad segments to the file.

• Open Run02. In the Record tab, select File > Add events from file:
