read.fs.surface.asc: Read FreeSurfer ASCII format surface.

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

Read FreeSurfer ASCII format surface.

Description

Read FreeSurfer ASCII format surface.

Usage

read.fs.surface.asc(filepath, with_values = TRUE, header_numlines = 2L)

Arguments

filepath	string. Full path to the input surface file in ASCII surface format.
with_values	logical, whether to read per-vertex and per-face values.
header_numlines	scalar positive integer, the number of header lines.

Value

named list. The list has the following named entries: "vertices": nx3 double matrix, where n is the number of vertices. Each row contains the x,y,z coordinates of a single vertex. "faces": nx3 integer matrix. Each row contains the vertex indices of the 3 vertices defining the face. WARNING: The indices are returned starting with index 1 (as used in GNU R). Keep in mind that you need to adjust the index (by substracting 1) to compare with data from other software.

Note

This is also known as *srf* format.
