Coordinates tracing 2D outlines of beaks (birds and squid)

<p>Two-dimensional coordinates for lines traced onto images of beaks.</p> <ul> <li>This is a .zip archive xy coordinates (250 files, .txt); and a list of specimen names (1 file, .csv).</li> <li>All images traced in FIJI.</li> <li>For each specimen, there is a trace of the beak rostrum and a separate trace of the beak bite surface.</li> <li>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.).</li> <li>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).</li> <li>All bird specimen images were downloaded from Phenome10k.org</li> <li>All cephalopod specimens were traced from images published in: <ul> <li>Xavier, J. C. &amp; Cherel, Y. 2009 Cephalopod beak guide for the Southern Ocean. British Antarctic Survey.</li> </ul> </li> </ul>
