All 108 subjects of OpenNeuro ds006233 (Picture naming, snapshot 1.0.0) have only ECOG channels in ses-1 channels.tsv (13,804 ECOG, 0 SEEG), so this dataset does not give SEEG data

An audit of the ses-1 BIDS channels.tsv metadata for all 108 subjects listed in OpenNeuro ds006233 (Picture naming) found 13,804 ECOG channels and 0 SEEG channels. The audit read only the channel type column; it did not inspect electrodes.tsv, EDF recordings, or sessions 2 and later. The result therefore applies to ses-1 channel metadata, and depends on the accuracy of that metadata. The archived report describes the analyzed data as snapshot 1.0.0, but its retrieval URL is a versionless S3 mirror; the exact release correspondence cannot be established from that URL alone. A separate, one-file check of ds005931 sub-01 ses-01 recorded 128 ECOG and 0 SEEG channels. The ds006233 row-level counts, downloaded TSV files, SHA256 hashes, and retrieval script are preserved with the original artifacts. The narrative reports 112 to 150 channels per subject and 128 in 79 subjects; the supplied row-level output also contains values outside that range, including 58, 64, and 164. No reconciliation was attempted.
