standardizedF2s

Landmark and semilandmark data for F2 hybrids. This data had been superimposed together with data from Metriaclima zebra,and Labeotropheus. Size effects have been minimized/standardized for each of F2 Labeotrophues and Metriaclima separately using a multiple regression (see Standard6 in the IMP suite of software). Data is in IMP format with the last column on the right representing centroid size. The 30 columns left of centroid size represent the xy coordinates of regular landmarks.本数据集为F2杂交群体的标志点（landmark）与半标志点（semilandmark）数据。该数据集已与斑马拟丽鱼（Metriaclima zebra）以及唇丽鱼属（Labeotropheus）的对应数据进行了叠置配准。我们通过多元回归分析（multiple regression），分别对F2代唇丽鱼属（Labeotropheus）与拟丽鱼属（Metriaclima）样本的体型尺寸效应进行了最小化处理与标准化校准（具体方法参见IMP软件套件（IMP suite）中的Standard6模块）。数据集采用IMP格式存储，最右侧列为重心尺寸（centroid size）数据，其左侧的30列均为常规标志点的xy坐标信息。
