Note that this reference documentation is identical to the help that is displayed in Matlab when you type “help ft_prepare_mesh_new”.

  FT_PREPARE_MESH_NEW creates a triangulated surface mesh for the volume
  conduction model. The mesh can either be selected manually from raw
  mri data or can be generated starting from a segmented volume
  information stored in the mri structure. The result is a bnd
  structure which contains the information about all segmented surfaces
  related to mri and are expressed in head coordinates.
 
  Use as
    bnd = ft_prepare_mesh(cfg, data)
 
  Configuration options:
    cfg.interactive     = 'no' (default) or 'yes' (manual interaction)
    cfg.tissue          = list with segmentation values/names corresponding with each compartment
    cfg.numvertices     = vector, length equal cfg.tissue.  e.g. [2000 1000 800];
    cfg.downsample      = (optional) integer (1,2, ...) defines the level of refinement of the mri data
    cfg.headshape       = a filename containing headshape, a Nx3 matrix with surface
                          points, or a structure with a single or multiple boundaries
    cfg.unit            = e.g. 'mm'
 
  To facilitate data-handling and distributed computing with the peer-to-peer
  module, this function has the following options:
    cfg.inputfile   =  ...
  If you specify one of these (or both) the input data will be read from a *.mat
  file on disk and/or the output data will be written to a *.mat file. These mat
  files should contain only a single variable, corresponding with the
  input/output structure.
 
  Example use:
 
    mri = ft_read_mri('Subject01.mri');
    cfg = [];
    cfg.output = {'scalp', 'skull', 'brain'};
    cfg.numvertices = [2000 1000 800];
    bnd = ft_prepare_mesh(cfg, segment);
