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

Create AFNI Format Metadata Object

Description

Creates an AFNIMetaInfo object containing format-specific metadata for AFNI format neuroimaging files.

Usage

AFNIMetaInfo(descriptor, afni_header)

Arguments

descriptor	AFNIFormat object specifying file format details
afni_header	List containing AFNI header information

Details

Create AFNIMetaInfo Object

The AFNIMetaInfo object extends MetaInfo with AFNI-specific features:

• AFNI brick structure

• Sub-brick labels and scaling

• Space transformation

• Statistical parameters

The function handles:

• Dimension extraction and validation

• Label generation for sub-bricks

• Transformation from AFNI to NIFTI space

• Data type and scaling setup

Value

An AFNIMetaInfo object

MetaInfo, read_afni_header

Examples

## Not run: 
# Read AFNI header
header <- read_afni_header("brain+orig.HEAD")

# Create format descriptor
fmt <- AFNIFormat()

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

# Check dimensions
dim(meta)

## End(Not run)
