    The test results of the SantaOmics algorithm. The mass peaks were extensively distorted in different ways, and the SantaOmics algorithm was applied to standardize the distorted mass spectra. The initial and distorted by multiplication (10×) mass spectra before ( a ) and after ( b ) standardization. Initial and linearly distorted (right corner is suppressed, left corner is powered) mass spectra before ( c ) and after ( d ) standardization.
