oh no! I recently recommended the morpho-tools to someone,
but - stupid me - I didn't check the link. I'd suggest that you write to
Jonathan Krieger and notify him about the defect link - he might probably even
send you a version of the program.
Alternatively, I think you could write to Norm McLeod, he will for sure be willing to give you a copy of his original software. He's the keeper of paleontology at the Natural History Museum in London, you can find his mail address here: http://www.nhm.ac.uk/hosted_sites/paleonet/MacLeod/MacLeodCV.pdf

Subject: extended eigenshape analysis for shark teeth
To: "[email protected]" <[email protected]>Hello everyone, I'm a master's student in geology at Tulane University. I'm planning on doing my master's thesis on morphometric techniques for identification of modern and fossil shark teeth. I have been using Iwata's SHAPE program for elliptic fourier analysis. After reading Dr. MacLeod's 1999 paper on eigenshape analysis ("Generalizing and Extending the Eigenshape Method of Shape Space Visualization and Analysis"), it seemed like his method of extended eigenshape analysis might be ideal for shark teeth, with three landmarks, one at the tip of the tooth, and two at the crown/root boundary on the outline. I would like to see how well this method differentiates species and higher taxonomic levels.My problem now is finding a software program to take my pictures, add the landmarks, and run the analysis so that it can be plotted with principal component analysis (or any x-y graph to visualize variation). On the website http://www.morpho-tools.net/ there is a link to download a program that Dr. Jonathan Krieger developed for his Ph.D for extended eigenshape analysis, but the link is broken. If anyone could help me with a link to this program, or with information about a similar program that performs the same function, I would be very grateful.I am not very familiar with morphometric techniques or statistics, so this is a slow learning process. I have read criticisms of elliptic fourier analysis that argue the lack of landmarks is a serious drawback, but landmark analysis that ignores curvature seems crude to me. I have become acquainted with Iwata's SHAPE program, and may continue to use it for my thesis, but Dr. MacLeod's method as described in his 1999 paper seemed ideal for shark teeth.My email address is [email protected] if anyone has any information they think might be helpful. Thanks in advance for helping out a novice in the field-
