Points can be labelled via ggrepel.\n+\n+In statistics, a `Volcano plot`_ is a type of scatter-plot that is used to quickly identify changes in large data sets composed of replicate data. It plots significance versus fold-change on the y and x axes, respectively. These plots are increasingly common in omic experiments such as genomics, proteomics, and metabolomics where one often has a list of many thousands of replicate data points between two conditions and one wishes to quickly identify the most meaningful changes. A volcano plot combines a measure of statistical significance from a statistical test (e.g., a p value from an ANOVA model) with the magnitude of the change, enabling quick visual identification of those data-points (genes, etc.) that display large magnitude changes that are also statistically significant.\n+\n+A volcano plot is constructed by plotting the negative log of the p value on the y axis (usually base 10). This results in data points with low p values (highly significant) appearing toward the top of the plot. The x axis is the log of the fold change between the two conditions. The log of the fold change is used so that changes in both directions appear equidistant from the center. Plotting points in this way results in two regions of interest in the plot: those points that are found toward the top of the plot that are far to either the left- or right-hand sides. These represent values that display large magnitude fold changes (hence being left or right of center) as well as high statistical significance (hence being toward the top).\n+\n+Source: Wikipedia\n+\n+-----\n+\n+**Inputs**\n+\n+A tabular file with a header row containing the columns below (additional columns may be present):\n+\n+ * P value\n+ * FDR / adjusted P value\n+ * Log fold change\n+ * Labels (e.g. Gene symbols or IDs)\n+\n+All points meeting the specified significance threshold will be labelled by default with the values in the Labels columns. Users can select to only label the top significant points under **Plot Options** or only to label certain points through providing a tabular labels file. The labels file must contin a header row and have the labels in the first column. These labels must match the labels in the main input file. If no labels are desired specify 0 for "Only label top most signifcant". If a log fold change (lfc) threshold is specified, points that meet the significance threshold and lfc threshold will be coloured red if upregulated and blue if downregulated.\n+\n+**Outputs**\n+\n+A PDF containing a Volcano plot like below.\n+\n+.. image:: $PATH_TO_IMAGES/volcano_plot.png\n+\n+.. _Volcano plot: https://en.wikipedia.org/wiki/Volcano_plot_(statistics)\n+\n+ ]]></help>\n+ <citations>\n+ </citations>\n+</tool>\n\\ No newline at end of file\n' |
