tab delimited text files can be loaded in excel or other spreadsheet viewers easily.

The following files contain the clustered mutants, transcripts, and full
data (log ratios) for the microarray data shown in Figure 2D.

Figure_2D_transcript_order.tab
Figure_2D_full_data.tab
Figure_2D__mutants_order.tab

Note that the clustered data is transposed from Figure 2D in the
manuscript, so it can be loaded on Excel.
