Recent advances in automation technologies have enabled the use of flow cytometry for high throughput screening, generating large complex data sets often in clinical trials or drug discovery settings. However, data management and data analysis methods have not advanced sufficiently far from the initial small-scale studies to support modeling in the presence of multiple covariates.
We developed a set of flexible open source computational tools in the R package flowCore to facilitate the analysis of these complex data. A key component of which is having suitable data structures that support the application of similar operations to a collection of samples or a clinical cohort. In addition, our software constitutes a shared and extensible research platform that enables collaboration between bioinformaticians, computer scientists, statisticians, biologists and clinicians. This platform will foster the development of novel analytic methods for flow cytometry.
The software has been applied in the analysis of various data sets and its data structures have proven to be highly efficient in capturing and organizing the analytic work flow. Finally, a number of additional Bioconductor packages successfully build on the infrastructure provided by flowCore, open new avenues for flow data analysis.
自动化技术的最新进展使得流式细胞术可用于高通量筛选,常在临床试验或药物研发环境中生成大量复杂数据集。然而,数据管理和数据分析方法与最初的小规模研究相比,进步不够显著,无法在存在多个协变量的情况下支持建模。
我们在R包flowCore中开发了一套灵活的开源计算工具,以促进对这些复杂数据的分析。其中一个关键组件是具有合适的数据结构,支持对一组样本或临床队列应用类似操作。此外,我们的软件构成了一个共享且可扩展的研究平台,能够促进生物信息学家、计算机科学家、统计学家、生物学家和临床医生之间的合作。该平台将推动流式细胞术新型分析方法的发展。
该软件已应用于各种数据集的分析,其数据结构已证明在捕获和组织分析工作流程方面非常高效。最后,一些额外的Bioconductor包成功地基于flowCore提供的基础设施构建,为流式数据分析开辟了新途径。
