FT_HEADMODEL_FNS
Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_headmodel_fns”.
FT_HEADMODEL_FNS creates the volume conduction structure to be used in the FNS forward solver. Use as headmodel = ft_headmodel_fns(seg, ...) Optional input arguments should be specified in key-value pairs and can include tissuecond = matrix C [9XN tissue types]; where N is the number of tissues and a 3x3 tensor conductivity matrix is stored in each column. tissue = see fns_contable_write tissueval = match tissues of segmentation input transform = 4x4 transformation matrix (default eye(4)) sens = sensor information (for which ft_datatype(sens,'sens')==1) deepelec = used in the case of deep voxel solution tolerance = scalar (default 1e-8) Standard default values for conductivity matrix C are derived from Saleheen HI, Ng KT. New finite difference formulations for general inhomogeneous anisotropic bioelectric problems.
