A question regarding volcano plot
Hello all,
I was trying to make a volcano plot with some real data, using log2(ratio)
vs. Z-value significance.
However the scatter of the points is too less contrary to 'normal' volcano
plots and I'm getting a sharp 'V' shaped plot.
*Am I doing something wrong here?*
The data(ratio) is available from pastebin:
