The research community has generated millions of datasets that were used to answer scientific questions of interest, and deposited those datasets into public data repositories as part of the mandated data sharing policies of funding agencies worldwide. Especially for datasets generated to measure the protein content of biological samples, substantial additional information can be extracted from these public datasets using newer techniques, newer versions of software, and newer reference information during re-analysis. This project will develop a software infrastructure for globally harmonized re-analysis of an emerging type of proteomics dataset to extract new information from older data. The infrastructure will improve our ability to turn proteomics data into knowledge about global relative protein abundances and about interactions between proteins inferred from how protein abundances are correlated. The project will also provide opportunities for students to learn skills in scientific data analysis. This project is an international collaboration with the Proteomics Team at EMBL-EBI (Hinxton, UK) and the Institute of Systems, Molecular and Integrative Biology (ISMIB) at the University of Liverpool (UoL; UK).This project will make the datasets generated by the method known as data-independent acquisition (DIA) mass spectrometry proteomics more findable, accessible, interoperable, and reusable (FAIR). This will be accomplished by developing an indexing system for the libraries of mass spectra that are used to analyze the data from DIA experiments. The project will further develop benchmarks and guidelines to advance the field, and then develop data analysis pipelines to process thousands of public experiments at scale and make the results available to the research community. The resulting protein abundance maps across thousands of experiments will enable the development of protein interaction maps via inference from protein co-expression patterns extracted from these datasets, something that can only be accomplished by thousands of datasets analyzed in unison. Students will be given opportunities to participate in the work in order to build their skills, and all software and data products will be made publicly available to further advance the field.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

研究界已经生成了数百万个用于回答感兴趣的科学问题的数据集，并将这些数据集存入公共数据库，作为全球资助机构强制数据共享政策的一部分。 特别是对于为测量生物样品的蛋白质含量而生成的数据集，可以在再分析期间使用更新的技术、更新版本的软件和更新的参考信息从这些公共数据集中提取大量附加信息。该项目将开发一个软件基础设施，用于对一种新出现的蛋白质组学数据集进行全球统一的重新分析，以便从旧数据中提取新信息。该基础设施将提高我们将蛋白质组学数据转化为关于全球相对蛋白质丰度以及从蛋白质丰度如何相关推断的蛋白质之间相互作用的知识的能力。该项目还将为学生提供学习科学数据分析技能的机会。 该项目是EMBL-EBI（Hinxton，UK）的蛋白质组学团队和利物浦大学（UoL; UK）的系统、分子和整合生物学研究所（ISMIB）的国际合作项目。该项目将使由称为数据独立采集（DIA）质谱蛋白质组学的方法生成的数据集更加可发现、可访问、可互操作和可重用（FAIR）。这将通过开发用于分析DIA实验数据的质谱库的索引系统来实现。该项目将进一步制定基准和指导方针，以推动该领域的发展，然后开发数据分析管道，以处理数千个大规模的公共实验，并将结果提供给研究界。在数千个实验中得到的蛋白质丰度图将通过从这些数据集中提取的蛋白质共表达模式进行推断来开发蛋白质相互作用图，这只能通过一致分析数千个数据集来完成。学生将有机会参与这项工作，以培养他们的技能，所有的软件和数据产品将公开提供，以进一步推动该领域的发展。该奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
