Data from: Organic epidermal and cellular preservation in a 290-million-year-old amphibian unveils tetrapod skin evolution

This dataset compiles the images and data used in the preparation of the manuscript “Organic epidermal and cellular preservation in a 290-million-year-old amphibian unveils tetrapod skin evolution” by Antoine Logghe and co-authors. The dataset is organized into three folders: Images_used_in_figure_panels: contains the images used in the figure panels presented in the manuscript. Raw_and_preprocessed_data: contains the raw images and data, as well as pre-processed data used to generate the figure panels. R_scripts: contains the R scripts used to plot and/or process some of the data, and to generate some of the figure panels. Metadata are documented in the filenames, which include identifiers for the corresponding figure panel, the data type, whether the file contains raw or processed data, and—when applicable—the location of point analyses. Detailed descriptions of the methods used to collect and generate the data are provided in the manuscript. The R scripts are fully commented to document the data processing and plotting steps. To execute them, only a single line specifying the working directory (i.e., the location where the data are stored) needs to be modified, after which the remainder of the code can be run.本数据集汇编了Antoine Logghe及其合著者所撰写的论文《2.9亿年前两栖动物的有机表皮与细胞保存揭示四足动物皮肤演化》（Organic epidermal and cellular preservation in a 290-million-year-old amphibian unveils tetrapod skin evolution）筹备过程中使用的图像与数据。 本数据集分为三个文件夹： Images_used_in_figure_panels：包含论文配图面板中使用的图像。 Raw_and_preprocessed_data：包含用于生成论文配图面板的原始图像、原始数据与预处理后的数据。 R_scripts：包含用于绘制部分图表、处理部分数据并生成部分配图面板的R脚本。 文件名中已附带元数据说明，其中包含对应配图面板的标识符、数据类型、文件为原始数据还是处理后数据，以及（如适用的）点位分析位置。数据采集与生成方法的详细说明已在论文中给出。 所有R脚本均附带完整注释，用于说明数据处理与绘图流程。仅需修改指定工作目录（即数据存储位置）的单行代码，即可运行其余全部代码。
