THALis: December 26 labeled recordings

Dec 26 files belong together: EEG + cues + about.txt. need to sort out the row/event counts and clock alignment before treating this as labeled data

Session artifacts: dec26lt1 and dec26lt2, committed the following day in bafc10e. Each has EEG data, a cue/trial sequence and setup/protocol material. The archived description names about.txt for experimental conditions.

Date rule: use December 26 as the recording date; December 27 is the commit date. Later folder names add _classification to distinguish these from rhythmic/sustained datasets.

Reference procedure: read about.txt, inspect EEG timestamps, and pair them with the cue file before epoching. The archive reports a 2,501-row file and 320 cue events for the first session, but does not provide enough timing detail here to infer one-to-one trial lengths or usable sample counts.

Review questions: are pre/post-cue samples retained, does the cue export include transitions other than task onset, and are clocks aligned? Treat these as labeled-session artifacts, not proof that all labels are already valid or all sessions are equivalent.
