read.fs.patch | R Documentation |
A patch is a subset of a surface. Note that the contents of ASCII and binary patch format files is different. A binary format patch contains vertices only, without connection (face) information. ASCII patch files can also contain face data. See the return value description for details.
read.fs.patch(filepath, format = "auto")
filepath |
string. Full path to the input patch file. An example file is 'FREESURFER_HOME/subjects/fsaverage/surf/lh.cortex.patch.3d'. |
format |
one of 'auto', 'asc', or 'bin'. The format to assume. If set to 'auto' (the default), binary format will be used unless the filepath ends with '.asc'. |
named list with 2 entries: "faces": can be NULL, only available if the format is ASCII, see return value of read.fs.patch.asc
. "vertices": numerical *n*x7 matrix. The columns are named, and appear in the following order: 'vert_index1': the one-based (R-style) vertex index. 'x', 'y', 'z': float vertex coordinates. 'is_border': integer, 1 if the vertex lies on the patch border, 0 otherwise (treat as logical). 'raw_vtx': integer, the raw vtx value encoding index and border. 'vert_index0': the zero-based (C-style) vertex index.
