build.mrtrix.header: Build the text header of an MRtrix streamlines file.

In freesurferformats: Read and Write 'FreeSurfer' Neuroimaging File Formats

Build the text header of an MRtrix streamlines file.

Description

MRtrix streamlines files (TCK for the tracks, TSF for per-point values along the tracks) share one header format, they only differ in the identifier line and in the meaning of the payload. The header is ASCII text, and its length is stored within the header itself as the offset at which the binary payload starts.

Usage

build.mrtrix.header(header_id, entries, datatype, count, offset)

Arguments

header_id	character string, the file type identifier, one of 'mrtrix tracks' (TCK) or 'mrtrix track scalars' (TSF).
entries	named list of additional header entries.
datatype	character string, the datatype.
count	integer, the number of streamlines.
offset	numeric, the byte offset at which the payload starts.

Value

character string, the header including the terminating newline.
