Raw outline coordinates

Morphometric data file in .nts format. This file contains 70 x- and y-coordinates of the raw 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格式的形态计量学数据文件。该文件收录了本研究中考察的全部87个微型钩子（micro-hooks）原始轮廓的70组x、y坐标，涵盖两次轮廓提取重复实验的结果（行标签中以".R1"与".R2"标记）。数据严格遵循.nts文件标准格式组织。文件首行存储元数据，第二行存储行标签，剩余各行均存储轮廓坐标。每行对应一个独立钩子。坐标以x、y配对形式排布：第三行首个数值为1号钩子首个轮廓点的x坐标，该行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。
