====== Volcano PLot ======

== Description ==

A volcano plot is a type of scatter-plot that is used to quickly identify changes in large datasets composed of replicate data. It plots significance versus fold-change on the y- and x-axes, respectively. A volcano plot combines a statistical test (e.g., T-test, ANOVA) with the magnitude of the change enabling quick visual identification of those data-points (genes, etc.) that display large-magnitude changes (over a Fold threshold) that are also statistically significant (under a P-value). For more information, see Wikipedia: [[http://en.wikipedia.org/wiki/Volcano_plot_(statistics)|Volcano_plot]], [[http://en.wikipedia.org/wiki/ANOVA|Anova]] and [[http://en.wikipedia.org/wiki/T-test|T-test]]
