MetaInfo-class: MetaInfo Class

Description

This class encapsulates meta information for neuroimaging data types, including spatial and temporal characteristics, data type, and labeling.

Slots

data_type

A character string specifying the data type code (e.g., "FLOAT", "INT").

dims

A numeric vector representing image dimensions.

spatial_axes

An AxisSet3D object representing image axes for spatial dimensions (x, y, z).

additional_axes

An AxisSet object representing axes for dimensions beyond spatial (e.g., time, color band, direction).

spacing

A numeric vector representing voxel dimensions in real-world units.

origin

A numeric vector representing the coordinate origin.

label

A character vector containing name(s) of images or data series.

Details

The MetaInfo class provides a structured way to store and access essential metadata for neuroimaging data. This includes information about the data type, spatial and temporal dimensions, voxel spacing, and coordinate system origin.

Examples

# Create a MetaInfo object
meta_info <- new("MetaInfo",
                 data_type = "FLOAT",
                 dims = c(64, 64, 32, 100),
                 spatial_axes = new("AxisSet3D"),
                 additional_axes = new("AxisSet"),
                 spacing = c(3, 3, 4),
                 origin = c(0, 0, 0),
                 label = "fMRI_run1")
