Webcontain chimeric spectra with more than 1 peptide in an estimated over 40% of spectra [1]. The CHIMERYS intelligent search algorithm rethinks the analysis of tandem mass spectra from the ground up by using artificial intelligence, including the accurate prediction of fragment ion intensities, to enable the deconvolution of complex chimeric spectra. WebJun 18, 2024 · The rate of successful identification of peptide sequences by tandem mass spectrometry (MS/MS) is adversely affected by the common occurrence of co-isolation and co-fragmentation of two or more isobaric or isomeric parent ions. This results in so-called `chimera spectra’, which feature peaks of the fragment ions from more than a single …
