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

     This function extracts genes forming the alpha cores of soft
     clusters

     acore(eset,cl,min.acore=0.5)

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

    eset: object of the class _exprSet_

      cl: An object of class 'flcust' as produced by 'mfuzz'.

min.acore: minimum membership values of  gene belonging to the cluster
          core

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

     The function produces an list of alpha cores  including genes and
     their membership values for the corresponding cluster.
