_D_e_s_c_r_i_p_t_i_o_n:

     The expression levels of approximately  4600 cellular RNA
     transcripts were assessed in CD4+ T cell lines at different  times
     after infection with HIV-1BRU using DNA microarrays. There are two
     data sets, which are part of a dye-swap experiment with
     replicates, representing the Cy3 (green) absorption intensities
     for channel 1 ('hiv1raw') and the Cy5 (red) absorption intensities
     for channel 2 ('hiv2raw').

_F_o_r_m_a_t:

     This data represents a block within a  microarray image with 12x32
     spots. It is stored as a vector of length 450,000 representing a
     450x1000 matrix (ordered by column) of intensities encoded for
     compact (16-bit TIFF) storage.

_D_e_t_a_i_l_s:

     The intensities can be obtained from this data by first 
     subtracting them from 65535, then squaring, then multiplying by  a
     scale factor 4.71542407E-05. In other words, a number 'x' in the
     'hiv1' data set corresponds to intensity   (256*256 - 1 -
     x)^2*.0000471542407 . \
