Manual channel checks found SEEG metadata in 1 of 37 ds003029 subject folders and only ECoG in checked ds006107 and ds005007 subjects

This publication reports a partial audit of SEEG eligibility in public OpenNeuro intracranial EEG (iEEG) datasets, using the BIDS `type` field in channels.tsv. Checks of current S3 files on 2026-10-10 found SEEG metadata in 1 of 37 ds003029 subject folders (sub-umf004, 125 SEEG channels); the other 36 folders had only ECOG and MISC. In ds006107, the checked sub-01 file had 116 ECOG channels; in ds005007, the checked sub-01 file had 74 ECOG channels and no events.tsv. File names in ds003029 all contained acq-ecog. These findings describe metadata labels and do not establish implant type where metadata may be inaccurate. The census script covered a list of 73 iEEG datasets but did not finish within the 45-minute run limit, so there are no all-dataset census tables. Only the first channels.tsv per subject is read, and S3 reflects current files rather than a fixed snapshot. The package includes the dataset list, the manual-check records, library usage counts, and Python standard-library code for listing datasets and performing the census.
