Coordinates tracing 2D outlines of beaks (birds and squid)
Two-dimensional coordinates for lines traced onto images of beaks. This is a .zip archive xy coordinates (250 files, .txt); and a list of specimen names (1 file, .csv). All images traced in FIJI. For each specimen, there is a trace of the beak rostrum and a separate trace of the beak bite surface. E...

| Summary: | Two-dimensional coordinates for lines traced onto images of beaks. This is a .zip archive xy coordinates (250 files, .txt); and a list of specimen names (1 file, .csv). All images traced in FIJI. For each specimen, there is a trace of the beak rostrum and a separate trace of the beak bite surface. Each trace file should be a list of xy coordinates that ends at the beak tip. This must be checked/verified/corrected for all files before running any analyses! I recommend visual inspection by plotting each beak dataset as a scatterplot in a color spectrum (rainbow, etc.). These were traced over pixel images, so each file has a different number of xy coordinates (depending on the pixel resolution/image size that was traced). All bird specimen images were downloaded from Phenome10k.org All cephalopod specimens were traced from images published in: Xavier, J. C. & Cherel, Y. 2009 Cephalopod beak guide for the Southern Ocean. British Antarctic Survey. Please email k.ritterbush@utah.edu with any questions. |
