FT_SOURCE2GRID
Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_source2grid”.
FT_SOURCE2GRID removes the fields from a source structure that are not necessary to reuse the dipole grid in another source estimation. Use as [grid] = ft_source2grid(source); The resulting grid can be used in the configuration of another run of FT_SOURCEANALYSIS. See also FTSOURCE2SPARSE, FT_SOURCE2FULL
