Volcano plots show the significance (typically negative log10 of the p-values adjusted for multiple testing, y-axis) against the change in gene expression (log2 fold change, x-axis). Additionally, the genes can be labelled using a gene name variable mapped onto 'labels'.
volcano_shiny - Original ShinyR implementation
This operator is an implementation based on VolcaNoseR.
The VolcaNoseR web app is a dedicated tool for exploring and plotting Volcano Plots. Users can explore the data with a pointer (cursor) to see information of individual datapoints. The threshold for the effect size (fold change) or significance can be dynamically adjusted. The plot can be annotated to show genes/proteins based on their top ranking or based on user input. More details about the VolcaNoseR app can be found in our publication
The plot can be saved as a PNG file or a PDF file, which can be opened and edited with Adobe Illustrator to allow for fine adjustments of the lay-out.
VolcaNoseR is created and maintained by Joachim Goedhart and Martijn Luijsterburg Bug reports and feature requests can be communicated in several ways:
