I need to create a heatmap out of this data but when i just use either
heatmap(data) or heatmap.2(data) all the colors are out of scale. i was
wondering
1) if there is any way of manipulating the data so that it will
become symmetrical so that repressed genes will appear in the correct shade
opposite to the one of upregulated genes.
2) i don't really understand how the DiffScore is calculated since the
difference the CTR and 1.25D3 AVG signal is not 15.91...any
explanation/suggestion would be awesome!

i didn't run the array myself and those are the data i was given.

thanks for the help!
