Question Posted 03/11/15:
Where can i find the patient's family identifier (FID) whose i know the subject identifier (Subject ID)?

Thank you in advance,
best regards.

There are no family identifiers in the ADNI study. AD family history is contained in the Family History Questionnaire table, however family members are not signed IDs.
