Peak Differences
Interpretation of mass spectra typically involves a seemingly never-ending check of the differences between all peaks in a spectrum. Peak Differences tool simply generates a table of differences between all the peaks in a peak list. This table can automatically search for masses of all amino acids, dipeptides or specified m/z value. Peak Differences tool therefore provides a useful utility for de novo peptide sequencing or PTM search.

Compare Peak Lists
Compare Peak Lists tool can be utilized to compare peak lists between multiple documents. Using this tool, one of the most typical and annoying manual task can be automatically performed within a few clicks. All of the opened documents are marked by its respective spectrum color and can be compared within a specified tolerance.

Spectrum Generator
In various situations, such as education, identification of peak overlaps or validation of different algorithms, it might be useful to generate an artificial mass spectrum to compare with acquired data or to test an algorithm capability. Using the Spectrum Generator tool you can model each peak of a given peak list as a gaussian-shaped curve with corresponding intensity, specified width and number of points per peak. To add more realistic look you can even apply some random noise of specified width.

Mass Filter
Remove typical mass spectra contaminants such as keratin or trypsin autolysis peptides by Mass Filter tool. Just choose one of the predefined reference lists or create your own. You can choose to remove all the matches peaks or just annotate them.
