Smoothed outline coordinates

Morphometric data file in .nts format. This file contains 70 x- and y-coordinates of the smoothed outlines of all 87 micro-hooks investigated in this study, across two replications of outline extraction (marked as ".R1" and ".R2" in the row labels). The data are provided as .nts file standard. The first line contains the metadata. The second line contains the row labels. The remaining lines contain the outline coordinates. Each line represents one individual hook. The coordinates are given in pairs of x and y. So the first value in the third line is the x-coordinate of the first outline point of hook number 1, the second value in the third line is the corresponding y-coordinate, the third value in the same line is the x-coordinate of the second outline point, the fourth value is the corresponding y-coordinate, and so forth.本数据集为.nts格式的形态测量数据文件。本文件涵盖本研究中所考察的全部87个微型挂钩（micro-hooks）经平滑处理后的轮廓的70组x、y坐标，对应两次轮廓提取重复实验，行标签中分别标注为".R1"与".R2"。本数据严格遵循.nts文件标准格式存储。文件首行存储元数据，第二行存储行标签，剩余各行存储轮廓坐标，每行对应一个独立的挂钩样本。坐标以x、y坐标对的形式排布：以第三行数据为例，该行首个数值为1号挂钩首个轮廓点的x坐标，第二个数值为其对应的y坐标；第三个数值为第二个轮廓点的x坐标，第四个数值为其对应的y坐标，依此类推。
