FAIRsharing record for: WIDDE

This FAIRsharing record describes: This next generation database is dedicated to the storage and management of dense genotyping data sets (up to several hundreds of thousands markers genotyped on thousands of individuals). It includes several utilities to select (on a population and/or marker location basis) data subsets, to perform basic data quality check and standard population genetics analyses (test of Hardy-Weinberg equilibrium, Principal Component Analysis) and to export the resulting datasets in various popular formats. Users can also upload their own genotyping data and explore them with data stored in WIDDE and assign new individuals to WIDDE populations using distance-based method and supervised hierarchical clustering. WIDDE contains public (freely accessible) and private (accessible via a login and password) data. The current version features cattle and sheep data but expect more to come!

本FAIRsharing记录（FAIRsharing record）所描述的下一代数据库，专门用于存储和管理高密度基因型数据集，可支持对数千个个体完成数十万个标记的基因分型。该数据库集成多项实用功能：可基于群体和/或标记位点筛选数据子集、执行基础数据质量检查与经典群体遗传学分析（包括哈迪-温伯格平衡（Hardy-Weinberg equilibrium）检验、主成分分析（Principal Component Analysis）），并可将处理后的数据集导出为多种主流格式。用户还可上传自有基因型数据，结合WIDDE存储的数据集进行探索分析，同时可通过基于距离的方法与监督层次聚类（supervised hierarchical clustering）将新个体归类至WIDDE群体中。WIDDE包含公开（可免费访问）与私有（需登录密码访问）两类数据，当前版本仅收录牛与绵羊的相关数据，后续将新增更多物种的数据！
