createNIfTIHeader: Create an Empty NIfTI-1 Header List

In bbuchsbaum/neuroim2: Data Structures for Brain Imaging Data

Create an Empty NIfTI-1 Header List

Description

Initializes a list of fields following the NIfTI-1 specification with default or placeholder values. Users typically call this internally via as_nifti_header rather than using directly.

Usage

createNIfTIHeader(oneFile = TRUE, file_name = NULL)

Arguments

oneFile	Logical; if TRUE, magic is set to "n+1" indicating a single-file (.nii) approach. Otherwise set to "ni1".
file_name	Optional character string to store in the header, usually referencing the intended output file name.

Details

This function sets up the skeleton of a NIfTI-1 header, including fields for diminfo, pixdim, qform_code, magic, etc. Most fields are initialized to zero, empty characters, or standard placeholders. The oneFile argument controls whether "n+1" or "ni1" is used for the magic field.

Value

A named list containing approximately 30 fields that comprise the NIfTI-1 header structure. Many of these are placeholders until filled by downstream usage.
