SUMMARY
We present LipidFinder online, hosted on the LIPID MAPS website, as a liquid chromatography/mass spectrometry (LC/MS) workflow comprising peak filtering, MS searching and statistical analysis components, highly customized for interrogating lipidomic data. The online interface of LipidFinder includes several innovations such as comprehensive parameter tuning, a MS search engine employing in-house customized, curated and computationally generated databases and multiple reporting/display options. A set of integrated statistical analysis tools which enable users to identify those features which are significantly-altered under the selected experimental conditions, thereby greatly reducing the complexity of the peaklist prior to MS searching is included. LipidFinder is presented as a highly flexible, extensible user-friendly online workflow which leverages the lipidomics knowledge base and resources of the LIPID MAPS website, long recognized as a leading global lipidomics portal.
AVAILABILITY AND IMPLEMENTATION
LipidFinder on LIPID MAPS is available at: http://www.lipidmaps.org/data/LF.
摘要
我们在 LIPID MAPS 网站上推出了在线版的 LipidFinder，它是一个包含峰过滤、MS 搜索和统计分析组件的液相色谱/质谱 (LC/MS) 工作流程，专门用于分析脂质组学数据。LipidFinder 的在线界面包括多个创新功能，如全面的参数调整、采用内部定制、整理和计算生成数据库的 MS 搜索引擎，以及多种报告/显示选项。该软件还包括一组集成的统计分析工具，使用户能够识别在所选实验条件下显著改变的特征，从而在进行 MS 搜索之前大大减少峰列表的复杂性。LipidFinder 作为一个高度灵活、可扩展的用户友好型在线工作流程，利用了 LIPID MAPS 网站的脂质组学知识库和资源，该网站长期以来一直被公认为全球领先的脂质组学门户。
