Metadata show SEEG channels in 13 of 14 OpenNeuro ds004194 subjects, but multiplexed files prevent SEEG-only downloads

A metadata-only census of OpenNeuro ds004194 found SEEG-typed channels in 13 of 14 subjects (416 unique channels, 360 marked good); all subjects also had ECoG channels. Eight SEEG subjects (p01 and p05–p11) had 56 temporalpattern runs, with 36 trials per run. In 52 runs with event_sample, events.tsv onset matched event_sample/sfreq within 0.05 ms; the six UMCU runs had event_sample marked n/a. The temporalpattern data use multiplexed BrainVision files, so byte-range requests cannot retrieve only SEEG channels. The SEEG subjects’ temporalpattern files total 1,384,554,252 bytes. The analysis used small BIDS metadata files only and did not download or analyze signals. Channel counts depend on curator type labels; the observed S3 state is dated 2026-10-11 and is not a fixed snapshot.

The OpenNeuro SEEG census showed which datasets have few AutoSci uses. We chose ds004194 from that gap and used the same curator type-label method.
