_D_e_s_c_r_i_p_t_i_o_n:

     This dataset contains basic chromosomal information for UCSC Human
     Genome Assembly May 2004 freeze. human.chrom.info.May04 is loaded
     automatically with the aCGH package.

_U_s_a_g_e:

     human.chrom.info.May04

_F_o_r_m_a_t:

     A data frame with 24 observations on the following 3 variables.

     _c_h_r_o_m Chromosomal index, X is coded as 23 and Y as 24.

     _l_e_n_g_t_h Length of each chromosome in kilobases.

     _c_e_n_t_r_o_m_e_r_e Location of the centromere on the chromosome (kb).


_D_e_t_a_i_l_s:

     This file is used for many plotting functions and needs to
     correspond to 'clones.info' mapping file. The centromeric location
     is approximately extimated by taking mid-point between the last
     fish-mapped clone on the p-arm and the first fish-mapped clone on
     the q-arm using relevant UCSC freeze. For an alternative freeze,
     one needs to manually create a 3-column file of the format
     described above.
