NIFTIMetaInfo: Create NIFTI Format Metadata Object

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

Create NIFTI Format Metadata Object

Description

Creates a NIFTIMetaInfo object containing format-specific metadata for NIFTI format neuroimaging files.

Usage

NIFTIMetaInfo(descriptor, nifti_header)

Arguments

descriptor	NIFTIFormat object specifying file format details
nifti_header	List containing NIFTI header information

Details

Create NIFTIMetaInfo Object

The NIFTIMetaInfo object extends MetaInfo with NIFTI-specific features:

• NIFTI header fields (qform, sform matrices)

• Data scaling (slope, intercept)

• File organization (separate vs. single file)

• Orientation information

Validation ensures:

• Valid NIFTI format

• Consistent dimensions

• Valid transformation matrices

• Proper data scaling

Value

A NIFTIMetaInfo object

Examples

## Not run: 
# Read NIFTI header
header <- readNIftiHeader("brain.nii")

# Create format descriptor
fmt <- NIFTIFormat()

# Create metadata
meta <- NIFTIMetaInfo(fmt, header)

# Check dimensions
dim(meta)

## End(Not run)
