Once the analysis is complete, open the resulting Feature list data node. Navigate to the Gene list section of the page and click on the volcano plot icon, located above on the header of a Fold change column left of the table header (Figure 1).

Each point on the plot represents the statistical result for a single feature (e.g. gene, transcript etc.). The black vertical and horizontal lines represent threshold of fold change and p-value respectively.  By By default the two vertical lines represent fold changes of -2 and +2, the horizontal line represents significant p-value of 0.05. The number of features Features that are up/down-regulated by at least 2 fold and have a p-value less than 0.05 are at the upper-right and lowerupper-left corner of the plot, they are highlighted in different colors. By default, significantly up-regulated features are in red, significantly down-regulated features are in green. The blue, and the remaining features are in grey or black (Figure 2). The plot header is derived from the name of the contrast.

You can manually configure the Y axis source from the drop-down list and change the threshold of p-value and fold change, then the position of the lines and number of features in the significant areas will be updated accordingly. Click on the Customize colors can manually change the color of the dots (features) in the different areas.

The Axes and Statistics menus allow to customize which data sources will be used for the axes as well as annotations, limits and significance thresholds for the plot (Figure 3).

The colors can also be customised using the Style menu (Figure 4).

You can also highlight and label any of the genes in the plot (Figure 5).
