Create NIFTI Format Metadata Object

Source: R/meta_info.R
NIFTIMetaInfo.Rd

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

Value

A NIFTIMetaInfo object

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

Examples


# Read NIFTI header
header <- read_header(system.file("extdata", "global_mask_v4.nii", package="neuroim2"))

# Create format descriptor
fmt <- new("NIFTIFormat",
           file_format = "NIFTI",
           header_encoding = "raw",
           header_extension = "nii",
           data_encoding = "raw",
           data_extension = "nii")

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

# Check dimensions
dim(meta)
#> [1] 64 64 25  4
