This data set contains mean and standard deviation information on the expression
levels of 5 transcripts (which were originated from 2 genes) at 10 time points
(0, 5, 10, 20, 40, 80, 160, 320, 640, 1280 mins) for three settings: 'gene',
'abstr' (absolute transcript), and 'reltr' (relative transcript) expression
levels. In addition, the fields 'gene_mapping' and 'time_mapping' includes
information which is useful to match the genes with transcripts and the time
points with data files, respectively.
