Foster_etal_2015_Heredity_MorphometricsData_Fig2.txt contains the raw data, formatted for the “tps” geometric morphometric software written by F. James Rohlf at Stony Brook University. Many other morphometrics programs can read data in this format. Each entry begins with the number of landmarks for a given specimen, and the subsequent lines of data are the x,y coordinates, in pixels, of the landmarks. The x,y coordinates are followed by a photo filename associated with each specimen (available upon request). The next line represents the unique specimen ID and the final line represents the scale in pixels/cm.
