Project Label
Participant Label
Experiment Label
The Experiment Label must be the Participant Label concatenated with the visit code, session code and modality code using underscores. It's important that the MRI or PET operator uses the experiment name as the patient name during an MRI or PET session.
Ex. ABC01_CMH_00000001_02_SE03_MR
| 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 Digits | 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 |
| 02 | Visit Code | 2 Digits | Increment each visit |
| SE03 | Session Code | SE followed by 2 Digits | Incement each session within a visit |
| MR | Modality Code | 2-4 Uppercase Letters | Must be chosen from the Modality Code List |
The Visit Code is 2 integers that represent the visit number. For example, 01 is first baseline visit, 02 is a follow-up visit, etc..
The Session Code is the letters 'SE' followed by 2 integers which distinguish different data capture sessions in a single visit. For example, if you are conducting an MRI experiment and you collect data before some intervention, the participant leaves the scanner for the intervention, then the participant returns to the scanner the session code should be incremented by 1. Notice the difference between visit and session where a visit denotes a participant coming to the institution for data acquisition where a session is denoted as a continuous acquisition of scans.
The Modality Code is 2 to 4 characters, denoting the modality with which the data was acquired. See the list of image modality codes below. For example, MR = Magnetic Resonance Imaging which includes fMRI, MRI, MRS etc.
