"Live a good life. If there are gods and they are just, they will not care how devout you have been, but will welcome you based on the values you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memory of your loved ones. I am not afraid."

@Hurda I'm afraid not - I've not used them myself, just found them by searching on the internet. Find one with some good reviews!

comment Negative value on linear gene expression in microarrays
Anything below the background threshold is by definition an unreliable signal (i.e. detection P-value > 0.05). The 2 options for dealing with this is either to set values below the background threshold to "missing", or to leave them in but be aware that below the background threshold the values are no longer meaningful (you might do this if, for instance, 60% of your sample were below background for this probe, but the rest were above - this is still meaningful because it means that 60% of your sample express less than the 40%, so you do not want to set them as missing, as this may be relevant

comment Negative value on linear gene expression in microarrays
This is pretty spot on. The "intensity" values you end up getting are relative values to the background levels. These tend to be normalized to an arbitrary value - "100" could be the arbitrary threshold for background, above which you see a reliable signal. A probe with very low intensity could therefore be below 0.
