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

Ex. ABC01_CMH_00000001

Example	Definitition	Restrictions/Rules	Notes
ABC	Project Code	3 Uppercase Letters	Chosen in coordination with KCNI admin. Preferably a project acronym. Cannot match existing project.
01	Study Code	2 Numerals	Typically '01', unless describing divisions within a project
CMH	Site Code	3 Uppercase Letters	Must be chosen from site code list HERE
00000001	Participant Code	4-8 Alphanumeric Characters	See 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.
