In OpenNeuro ds003876 v1.0.2, channel metadata classify 30 of 39 subjects as SEEG; only 1 SEEG subject has sleep and wake runs, and 5 ECoG subjects have run-dependent SOZ labels

A metadata audit of all 54 BIDS *_channels.tsv files in OpenNeuro ds003876 v1.0.2 covered 39 subjects. Thirty subjects had only SEEG-typed channels and 9 had only ECoG-typed channels. Ten subjects had both an interictalasleep and an interictalawake run: 9 ECoG subjects and 1 SEEG subject (umf004). Thus this dataset supports a within-subject SEEG sleep/wake test in only one subject. Each SEEG subject had one interictal run whose state was not labelled. In five multi-run ECoG subjects (jh103, jh105, pt1, pt2, pt3), the channels labelled soz = yes differed between runs (19 vs 31, 26 vs 35, 10 vs 35, 8 vs 31, and 31 vs 41); in each case the smaller set was a subset of the larger set. The audit examined channel metadata only, not signals or electrode images, and used channel types as set by dataset curators. A preregistered wake/sleep aperiodic-exponent analysis was not completed, so no signal result is claimed. Full run-level counts and subject-level SOZ consistency results are included with the source files.
