mzCloud is a curated mass spectral database of high-resolution tandem mass spectra arranged into spectral trees. It supports spectrum, tree, structure, substructure, m/z, and compound name searches, and is intended to help identify compounds, including those not present in the library. The database includes annotated fragments, molecular formulas, identifiers, and experimental metadata. It is an open consortium effort covering fields such as metabolomics and toxicology.
PeptideAtlas is a multi-organism, publicly accessible compendium of peptides identified in tandem mass spectrometry proteomics experiments. Each atlas build is made by searching spectra against sequence databases or spectral libraries, assigning probabilities to peptide-spectrum matches and selecting matches that pass a threshold. Builds are named for a species or subproteome, such as Human Plasma, and the search function covers only default builds.
An illustrated explainer article on VQGAN, describing how the model generates images from text at a conceptual level and how VQGAN and CLIP work in tandem. It covers a theory of perception, using transformers to model interactions, expressing images through a codebook, and training the GAN and transformer.
