The participant label must be the concatenation of the Project Label, an underscore and a Participant Code.

Ex. ABC01_CMH_00000001

ExampleDefinititionRestrictions/RulesNotes
ABCProject Code3 Uppercase LettersChosen in coordination with KCNI admin. Preferably a project acronym. Cannot match existing project.
01Study Code2 NumeralsTypically '01', unless describing divisions within a project
CMHSite Code3 Uppercase LettersMust be chosen from site code list HERE
00000001Participant Code4-8 Alphanumeric CharactersSee recommendations below

The Participant Code denotes a specific person (or animal) within the study:

  • must be 4 to 8 characters long
  • preferably contains only numeric digits, but can include uppercase letters if needed
  • 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 subject. (eg. BAD: ABC01_CMH_V10001 - where V1 represents the first visit)

If you have already started collecting data and your subjects do not follow this naming convention, please indicate this at your Neuroinformatics Platform project on-boarding meeting as a name conversion script might need to be implemented.
