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

     This function parses a CDF file using the Affymetrix Fusion SDK.

     _This function will most likely be replaced by the more general
     'readCdfUnits()' function._

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

       readCdf(filename, verbose = 0)

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

filename: name of the CDF file.

 verbose: how verbose should the output be. 0 means no output, with
          higher numbers being more verbose.

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

     A list with one component for each unit. Every component is again
     a list with three components     

  groups: This is again a list with one component for each group (also
          called block). The information on each group is a list with 5
          components, 'x', 'y', 'pbase', 'tbase', 'expos'.

    type: type of the unit.

direction: direction of the unit.

_N_o_t_e:

     This version of the function does not return information on the QC
     probes. This will be added in a (near) future release. In addition
     we expect the header to be part of the returned object.

     So expect changes to the structure of the value of the function in
     next release. Please contact the developers for details.

     Hansen, khansen@stat.berkeley.edu

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

     'affxparserInfo' for general information about the package/Fusion
     SDK and 'readCdfHeader()' for getting the header of a CDF file.
