Using proper KCNI naming convention to label projects, participants, experiments, and files is extremely important as data is routed through the Neuroinformatics Platform according to these labels. Please take great case in ensuring data is properly labelled at every level, codes are consistent throughout the project life cycle and typos are avoided. Thank you!

Project Label

Study Participant

ID

Experiment Label

NOTE: It's important that the MRI or PET operator use the Experiment Label as the Patient Name in the DICOM header during an MRI or PET session.

Please ensure the Experiment Label is entered correctly at all data entry occurences as a misspelled Experiment Label can have significant consequences throughout the Neuroinformatics Platform system.

The Experiment Label must be the Study Participant Label ID concatenated with the visit code, session code and modality code using underscores.

Ex. ABC01_CMH_00000001_02_SE03_MR

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.

EEG Data Filename

When saving an EEG data file that is to uploaded by automated data upload processes in XNAT it is important to properly label the file to ensure the data can be organized into its proper XNAT storage location.

The data files should follow the Experiment Label convention followed by an underscore, then a trial code.

Ex. ABC01_CMH_00000001_02_SE03_EEG_rest.cnt

The Trial code is usually used to describe different runs within a session. For example rest is common to describe continuous resting data. Other popular examples are single or lici for TMS trials and 1Back, 0Back, etc. for NBack trials.

Notes:

• DO NOT use commas, periods, underscores, spaces, dashes, slashes or other punctuation in the trial code. Instead use camel case (ex. thisIsACamelCaseExample)
• Ensure that the trial code is consistent across experiments and scans. For example, using 0Back, zeroBack or 0back will cause errors later on

Phantom Naming Convention

Phantom data is used in imaging studies to measure scanner variability over time. On the KCNI XNAT, phantom data must be labelled slightly differently compared to in-vivo data. 

Phantom Participant Label

The Phantom Participant Label must be the concatenation of the Project Label and the combination of the phantom type with the phantom identifier joined by an underscore.

Ex. ABC01_CMH_LEGPHA

The Phantom Type is a 3 character code that describes the construction of the phantom. This code must be chosen from the Phantom Types List below. Ex: LEG = Lego phantom

The Phantom Identifier is the letters 'PHA' that identifies the subject as a phantom

Phantom Experiment Label

The Phantom Experiment Label must be the Phantom Experiment Label concatenated with the session code and modality code using underscores.

Ex. ABC01_CMH_LEGPHA_200511_MR

The Phantom Date code is 6 digits representing the date of your scan (ex. yymmdd).

The Modality code is the same as the human Modality code. It is a string of 2 to 4 characters which denotes the modality with which the data was captured.

Modality Codes

Anchor
modalityCodes modalityCodes

The Modality Code denotes the apparatus with which the imaging data was acquired and is appended to the end of the Experiment Label. Only Modality Codes chosen from the list below are considered acceptable. If you are collecting data that is not well described by one of the listed modalities, please contact XNAT Admin and your imaging modality can be added.

Phantom Type Codes

Anchor
phantomCodes phantomCodes

Below is a list of acceptable Image Phantom Types. If you have a phantom that is not well described by one of the codes in this list, then please contact XNAT Admin and your phantom can be added.
