write.fs.surface.bvsrf(
  filepath,
  vertex_coords,
  faces,
  normals = NULL,
  neighborhoods = NULL
)

Arguments

filepath

string. Full path to the output curv file. If it ends with ".gz", the file is written in gzipped format. Note that this is not common, and that other software may not handle this transparently.

vertex_coords

n x 3 matrix of doubles. Each row defined the x,y,z coords for a vertex.

faces

n x 3 matrix of integers. Each row defined the 3 vertex indices that make up the face. WARNING: Vertex indices should be given in R-style, i.e., the index of the first vertex is 1. However, they will be written in FreeSurfer style, i.e., all indices will have 1 substracted, so that the index of the first vertex will be zero.

normals

matrix of nx3 vertex normals (x,y,z)

neighborhoods

list of integer lists, the indices of the nearest neighbors for each vertex (an adjacency list). The sub list at index n contains the indices of the vertices in the 1-neighborhood of vertex n. The vertex indices in the sub lists must be zero-based.

Note

This function is experimental. Only SRF file format version 4 is supported.
