Hello, I'm attempting to organize proper IRB approval in my institution for work on the Mt. Sinai Brain Bank dataset (syn3159438) and the ROS-MAP (syn3219045) dataset. One of the questions I'm asked by my institution is if these datasets are de-identified meaning that they do not contain any identifiers or unique codes that link to a master key. If any of these datasets indeed do contain a directly identifiable format or coded format can you please help me identify which one so I can complete the proper IRB paperwork? Thank you very much in advance. @qfelty @Feltyq My Best, Christian
