Researchers have developed MARLIN, a novel computational method for elucidating molecular structures directly from tandem mass spectrometry data without requiring a known molecular formula. This approach is particularly useful for identifying unknown compounds in biological samples, which are crucial for drug discovery and biomarker research. MARLIN utilizes a self-supervised encoder to predict molecular fingerprints and a diffusion language model to generate candidate structures, ensuring mass accuracy without pre-determining the atom inventory. The method demonstrates strong performance on the NPLIB1 benchmark, outperforming other formula-agnostic techniques in accuracy and structural similarity. AI
