lta.volume.info.lines: Write the volume info section of an LTA file.

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

Write the volume info section of an LTA file.

Description

The volume info section records the geometry of one of the two volumes an LTA file relates: its dimensions, voxel sizes and the direction vectors and center that describe its RAS space. The geometry is written from a volume descriptor, and the direction vectors are the columns of its voxel-to-RAS matrix while the center is the RAS coordinate of voxel index dim/2, which is what FreeSurfer records there.

Usage

lta.volume.info.lines(descriptor, section_name)

Arguments

descriptor	NULL or a volume descriptor, see volume.descriptor.
section_name	character string, either 'src' or 'dst'.

Value

character vector, the lines of the section.
