Fig. 2

Displays the primary figures obtained from the protein section of PTMViz. a The top figure displays a volcano plot with the log2 fold change on the x-axis and either the p value or the FDR adjusted p value on the y-axis depending on the options selected. The points on the plot are interactive such that hovering the cursor over each individual point shows the protein Uniprot id, gene id, description, log2 fold change, and p value. Proteins that are identified as significant based on user defined thresholds (dashed lines) are highlighted in red. Modifying proteins that match to the WERAM database are highlighted in blue. Multiple points on the graph can be selected and viewed in the primary table to allow for the export of points of interest. b A heatmap of the z-score scaled log2 normalized protein intensities for the proteins identified as significant in the Volcano plot
