Stratigraphic correlation underpins all understanding of Earth’s history, yet few geoscientists have access to, or expertise in, numerical codes that can generate reproducible, optimal (in a least-squares framework) alignments between two stratigraphic time-series data sets. Here we introduce Align, a user-friendly computer app that makes accessible a published dynamic time warping (DTW) algorithm that, in a minute or less, catalogs a library of alignments between two time-series data sets by systematically exploring assumptions about the temporal overlap and relative sedimentation rates between the two stratigraphic sections. The Align app, written in the free, open-source R programming language, utilizes a graphical user interface (e.g., drop-down menus for data upload and sliding bars for parameter exploration) such that no coding is required. In addition to generating alignment libraries, a user can employ Align to visualize, explore, and cull each alignment library according to thresholds on Pearson’s correlation coefficient and/or temporal overlap. Here we demonstrate Align with time-series records of carbonate stable carbon isotope composition, though Align can, in principle, align any two quantitative stratigraphic time-series data sets.
地层相关性是了解地球历史的基础，然而很少有地球科学家能够使用或掌握数字代码的专业知识，这些代码能够在两个地层时间序列数据集之间生成可重复的最佳（最小二乘框架）排列。在这里，我们介绍 Align，这是一个用户友好型计算机应用程序，它可以使用已发布的动态时间扭曲（DTW）算法，通过系统地探索两个地层剖面之间的时间重叠和相对沉积速率假设，在一分钟或更短的时间内为两个时间序列数据集之间的排列库编目。Align 应用程序由免费开源的 R 编程语言编写，采用图形用户界面（如用于数据上传的下拉菜单和用于参数探索的滑动条），因此无需编码。除了生成配对库之外，用户还可以利用 Align 根据皮尔逊相关系数和/或时间重叠的阈值对每个配对库进行可视化、探索和筛选。在这里，我们用碳酸盐岩稳定碳同位素组成的时间序列记录来演示 Align，尽管 Align 原则上可以对任何两个定量地层时间序列数据集进行配准。
