mzCloud
收藏资源简介:
mzCloud is an extensively curated database of high-resolution tandem mass spectra that are arranged into spectral trees. MS/MS and multi-stage MSn spectra were acquired at various collision energies, precursor m/z, and isolation widths using Collision-induced dissociation (CID) and Higher-energy collisional dissociation (HCD). Each raw mass spectrum was filtered and recalibrated giving rise to additional filtered and recalibrated spectral trees that are fully searchable. Besides the experimental and processed data, each database record contains the compound name with synonyms, the chemical structure, computationally and manually annotated fragments (peaks), identified adducts and multiply charged ions, molecular formulas, predicted precursor structures, detailed experimental information, peak accuracies, mass resolution, InChi, InChiKey, and other identifiers. mzCloud is a fully searchable library that allows spectra searches, tree searches, structure and substructure searches, monoisotopic mass searches, peak (m/z) searches, precursor searches, and name searches. mzCloud is free and available for public use online.
mzCloud 是一个经过广泛精炼的高分辨率串联质谱数据库,其数据按照光谱树的形式组织。通过使用碰撞诱导解离(CID)和更高能量的碰撞解离(HCD)技术,在不同的碰撞能量、前体质荷比(m/z)和隔离宽度下采集了 MS/MS 和多级 MSn 光谱。每个原始质谱经过过滤和重新校准,从而产生了可完全检索的附加过滤和重新校准的光谱树。除了实验和加工数据之外,每个数据库记录还包含化合物名称及其同义词、化学结构、计算和手动注释的碎片(峰)、已识别的加合物和多重电荷离子、分子式、预测的前体结构、详细的实验信息、峰精度、质量分辨率、InChi、InChiKey 以及其他标识符。mzCloud 是一个可完全检索的库,它允许进行光谱搜索、树搜索、结构及子结构搜索、单同位素质量搜索、峰(m/z)搜索、前体搜索以及名称搜索。mzCloud 是免费且可供公众在线使用的。
