========

This glossary provides definitions of key terms used throughout the tutorial.

**Account**  
    User access credentials and authentication needed to interact with the QMENTA Platform.

**Analysis**
    A single analysis or workflow of sequential analyses which can be executed
    in the QMENTA Platform (e.g., FreeSurfer, Protocol Adherence Automation,
    Medical Image Data analysis, etc.).


**Analysis ID**
    A unique identifier assigned to an Analysis. An Analysis will always have a Analysis ID.

**Analysis Log**
    Log generated during the execution of the analysis.

**Application Programming Interface (API)**
    A set of methods that allow communication with the QMENTA Platform programmatically.

**Container ID**
    A unique identifier for a storage unit where session data or analysis outputs are stored.
    Note a Container ID is only assigned to a Patient ID or Analysis ID if they are storing files.

**Metadata**
    Numerical and qualitative data associated with a session (Subject ID/Session ID)
    or a file within a session in a Project in the QMENTA Platform.
    Some examples are the file modality, acquisition parameters, and/or clinical scores.

**Modality**
    A label automatically or manually added to a data file in the QMENTA Platform.
    It corresponds to the imaging modality of the data file in the broad sense (e.g., CT, PET, DTI, T1, T2, etc... ).

**Patient ID**
    A unique identifier assigned to a session. Note a session always has a Patient ID.

**Project**
    The imaging data and the corresponding analyses are organized by Project
    in the QMENTA Platform. Each Project is a separate entity and information (data and metadata) is
    not shared across Projects.

**QC Status**
    A quality check label assigned to a session or analysis, indicating whether
    the quality check has passed, failed, or if it is undetermined.

**Search Criteria**
    A dictionary of parameters used to perform data and metadata searches on a Project.

**Subject**
    An individual whose cross-sectional and/or longitudinal imaging data is in the QMENTA Platform.

**Subject ID**
    A name assigned to a subject in a Project. It must be unique across subjects.

**Session**
    The imaging data of a Subject at a single timepoint.

**Session ID (SSID)**
    Numerical identifier of an imaging session associated with a subject (Subject ID) in a QMENTA Platform Project.
    The pair Subject ID/Session ID uniquely identifies every imaging session in a QMENTA Platform Project.
    Note the Session ID must be unique for a given Subject ID.

**Tag**  
    A label manually or automatically assigned to a session or a file to categorize it.

**Timepoint**
    An imaging session acquired at a specific moment in time.
    This corresponds to a Subject ID/Session ID and may include Metadata.

**Workflow**
    A sequence of image processing analysis executed in the QMENTA Platform.
