New rules that determine how study IDs are assigned to images archived within the IDA have been implemented. As a part of this change, many existing records have been reassigned study IDs. This may impact you if you use LONI Study IDs for internal purposes and/or for reporting your analysis results. A listing of study ID changes, showing original LONI study ID and revised LONI study ID, is available from within the IDA download section (under Imaging –> MR Image Quality).
NOTE: LONI study ID is also called LONISID in several ADNI datasets.
