Excerpt

It is important that each project Subject is assigned exactly 1 Subject ID that is unique across the project. In multi-site or multi-modality projects, care must be taken to ensure the same Subject is not assigned multiple Subject IDs at different sites or across different modalities. Of equal importance is the precise Subject ID entry at every data entry occurence. A Subject ID typo can have significant consequences throughtout the Neuroinformatics Platform system.

  • recomended to start at 00000001 and increment as necessary
  • must not contain lowercase letters, symbols, or whitespace (spaces, tabs, etc)
  • must not include PHI (e.g., diagnosis), case/control status, or other sensitive information
  • must not contain the characters 'PHA' in positions 4-6, since these indicate "phantom" (non-human) images in XNAT
  • must not contain any coding related to location, visit, or any other code that is not representative of the
