The visualization capabilities of the jHRMS toolbox are another unique feature and will also be extensively showcased in workflow I and II. At almost every point of the workflow the data can be visualized and inspected, ranging from the more standard raw data visualization to post-processing extracted data (i.e., features, components, identifications, suspects, and alignments). The detected features can be visualized on a heatmap of the chromatogram with which the user can interact and pull up the corresponding plots of the MS1 and MS2 scans. On the other hand, the raw data from the time and mass domains behind specific features or components can be plotted, allowing the user to inspect the quality of extracted information. Additionally, suspect screening and identification matches can also be visualized to perform post-processing quality control, showing both the matching performance in the time and mass domain. More advanced features are the possibility to plot the Kendrick masses for feature lists and aligned files and the possibility to plot the alignment of features, components, and suspects.
