_D_e_s_c_r_i_p_t_i_o_n:

     The method creates estimates of the fractional anisotropy (FA) and
     relative anisotropy (RA) indices, the main directions of
     anisotropy and several statistics used for visualization.

_U_s_a_g_e:

       ## S4 method for signature 'dtiTensor':
       dtiIndices(object, which)

_A_r_g_u_m_e_n_t_s:

  object: Object of class '"dtiTensor"' 

   which: Indices should be created, currently not implemented. 

_V_a_l_u_e:

     An object of class '"dtiIndices"'.

_M_e_t_h_o_d_s:



     _o_b_j = "_A_N_Y" Returns a warning. 

     _o_b_j = "_d_t_i_T_e_n_s_o_r" Estimate tensor indices like trace, fractional
          and geodesic anisotropy, main diffusion direction and shape
          parameters.
