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

     Reconstructs signal from ridges obtained by `crc', using the
     restriction of the transform to the ridge.

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

     scrcrec(siginput, tfinput, beemap, bstep=5, ptile=0.01, plot=2)

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

siginput: input signal. 

 tfinput: time-frequency representation (output of `cwt' or `cgt'. 

  beemap: output of crazy climber algorithm 

   bstep: used for the chaining (see `cfamily'). 

   ptile: threshold on the measure beemap (see `cfamily'). 

    plot: 1: displays signal,components, and reconstruction one after
          another.
          2: displays signal, components and reconstruction.
          Else, no plot. 

_D_e_t_a_i_l_s:

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

     Returns a list containing the reconstructed signal and the chained
     ridges. 

     rec: reconstructed signal

 ordered: image of the ridges (with different colors)

    comp: 2D array containing the signals reconstructed from ridges

_R_e_f_e_r_e_n_c_e_s:

     See discussions in the text of ``Practical Time-Frequency
     Analysis''.

_S_e_e _A_l_s_o:

     `crc',`cfamily' for crazy climbers method, `crcrec' for
     reconstruction methods.
