MetaInfo-class: MetaInfo Class

In bbuchsbaum/neuroim2: Data Structures and IO for Neuroimaging Data with an Emphasis on Functional Magnetic Resonance Imaging (FMRI)

MetaInfo Class

Description

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

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.

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.

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")
