Abstract Systems and methods are provided for predicting the mass spectrum of an unknown compound. An experimental mass spectrum of a known compound is obtained. One or more mass peaks of the experimental mass spectrum corresponding to a substructure of the known compound are annotated with at least one modification an unknown compound is predicted to include. An in- silico mass spectrum is created for the unknown compound from the experimental mass spectrum and the annotated one or more mass peaks. The unknown compound is then identified from a sample by mass analyzing the sample, producing an unknown experimental mass spectrum, and comparing the unknown experimental mass spectrum to the in-silico mass spectrum. L'invention concerne des systèmes et des procédés permettant de prédire le spectre de masse d'un composé inconnu. Un spectre de masse expérimental d'un composé connu est obtenu. Un ou plusieurs pics de masse du spectre de masse expérimental correspondant à une sous-structure du composé connu sont annotés avec au moins une modification dont on prédit qu'elle est incluse dans un composé inconnu. Un spectre de masse in silico est créé pour le composé inconnu à partir du spectre de masse expérimental et des un ou plusieurs pics de masse annotés. Le composé inconnu est ensuite identifié à partir d'un échantillon par analyse de masse de l'échantillon, production d'un spectre de masse expérimental inconnu et comparaison du spectre de masse expérimental inconnu au spectre de masse in silico.
