MAPPING THE PRENATAL GROWTH OF THE MANDIBLE

This repository contains all geometrical data and metadata belonging to the paper MAPPING THE PRENATAL GROWTH OF THE MANDIBLE by the MAGIC Amsterdam research consortium. NaN values are used throughout when values were unknown or unavailable. The following contents are uploaded: fetal_coordinates.csv | 14 x 126 matrix containing the 3-dimensional coordinates of the annotated landmarks of the 42 samples, where the rows are landmarks and the columns are x-, y-, and z-coordinates of the 42 samples formatted [x1, y1, z1, x2, y2, z2, ..., x42, y42, z42]. The order of the landmarks is:1 right coronoid2 right condyle, buccal point3 right condyle, cranial point4 right condyle, lingual point5 right condyle, posterior point6 right gonion7 right menton8 left coronoid9 left condyle, buccal point10 left condyle, cranial point11 left condyle, lingual point12 left condyle, posterior point13 left gonion14 left menton fetal_measurements.csv | 42 x 11 matrix where rows are samples and columns are measurements. The order of the measurements is:1 body length, right2 body length, left3 ramus height, right4 ramus height, left5 gonial angle, right6 gonial angle, left7 bigonial width8 bicondylar width9 body length, left and right average10 ramus height, left and right average11 gonial angle, left and right average fetal_metadata.csv | This matrix contains the sample code (first column), age in days (second column) and biological sex (third column, 1 = male and 2 = female) for all samples (rows).本数据集仓库包含阿姆斯特丹MAGIC研究联盟发表的论文《下颌骨产前生长图谱绘制》（MAPPING THE PRENATAL GROWTH OF THE MANDIBLE）所涉及的全部几何数据与元数据。当数值未知或无法获取时，全程使用NaN（非数值，Not a Number）标记缺失值。本次上传的内容如下： 1. fetal_coordinates.csv：该文件为14×126矩阵，存储42个样本的标注解剖标志点（annotated landmarks）的三维坐标。其中行代表标志点，列按[x₁, y₁, z₁, x₂, y₂, z₂, ..., x₄₂, y₄₂, z₄₂]的格式排列，对应42个样本的x、y、z轴坐标。标志点的顺序如下： 1. 右侧冠突 2. 右侧髁突颊侧点 3. 右侧髁突颅侧点 4. 右侧髁突舌侧点 5. 右侧髁突后点 6. 右侧下颌角点 7. 右侧颏点 8. 左侧冠突 9. 左侧髁突颊侧点 10. 左侧髁突颅侧点 11. 左侧髁突舌侧点 12. 左侧髁突后点 13. 左侧下颌角点 14. 左侧颏点 2. fetal_measurements.csv：该文件为42×11矩阵，行代表样本，列代表各项测量指标。测量指标的顺序如下： 1. 右侧下颌体长度 2. 左侧下颌体长度 3. 右侧升支高度 4. 左侧升支高度 5. 右侧下颌角角度 6. 左侧下颌角角度 7. 双侧下颌角间距 8. 双侧髁突间距 9. 左右侧下颌体平均长度 10. 左右侧升支平均高度 11. 左右侧下颌角平均角度 3. fetal_metadata.csv：该矩阵存储所有样本（行）的元数据，其中第一列为样本编码，第二列为胎龄（单位：天），第三列为生物学性别（1代表男性，2代表女性）。
