The Experiment name must be the participant ID 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.
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.
The Modality code is 2 to 4 characters, denoting the modality with which the data was captured. See the list of image modality codes below. For example, MR = Magnetic Resonance Imaging.
