动机:实验空间蛋白质组学,即根据定量蛋白质组学数据将蛋白质高通量分配到亚细胞间,如果有足够的计算工具,有望为许多生物过程提供新的线索。结果:我们在这里介绍了pRoloc,一个完整的基础设施,以支持和指导基于定量质谱学的空间蛋白质组学数据的合理分析。它提供无监督和有监督的机器学习功能,用于数据探索、蛋白质分类和新颖性检测,以识别新的假定亚细胞簇。该软件建立在现有的数据管理和数据处理基础设施之上。可获得性:pRoloc以R语言实现,并根据BioConductor项目(http://www.bioconductor.org/).)的开放源码许可提供该包中包含介绍数据导入/导出和分析的完整教程的小插曲。测试数据可以在配套的包pRolocdata中获得。联系方式:lg390@cam.ac.uk
Motivation: Experimental spatial proteomics, i.e. the high-throughput assignment of proteins to sub-cellular compartments based on quantitative proteomics data, promises to shed new light on many biological processes given adequate computational tools. Results: Here we present pRoloc, a complete infrastructure to support and guide the sound analysis of quantitative mass-spectrometry-based spatial proteomics data. It provides functionality for unsupervised and supervised machine learning for data exploration and protein classification and novelty detection to identify new putative sub-cellular clusters. The software builds upon existing infrastructure for data management and data processing. Availability: pRoloc is implemented in the R language and available under an open-source license from the Bioconductor project (http://www.bioconductor.org/). A vignette with a complete tutorial describing data import/export and analysis is included in the package. Test data is available in the companion package pRolocdata. Contact: lg390@cam.ac.uk
