My name is Louise Waßermann. I`m writing my diploma thesis at the university of Leipzig (Germany) at the instituite of biology (AG spezielle Zoologie). I`m investigating the population structure of Microtus arvalis in Germany by sequencing a part of the cytb and the control region. I also want to use geometric morphometrics. I already started with taking pictures from the mandible and from the second molar of the mandible. I have used the program tpsDig2 to set 15 landmarks on the mandible. But I don`t know what to do next. I have downloaded all the tps programs. I want to generate the distributions of centroid sizes among the studied populations (which is no problem) and I want to create scatterplots of the first two canonical variate scores calculated from landmarks and it would be good to show the results by deformation grids. The problem is that I do not know how to do this canonical variate analysis. Which statistical tests should I use before? Which values do I use for the canonical variate analysis. I have bought me the book "Geometric Morphometrics for biologists", A Primer but it just gives the theoretical background. I need somthing practical. Nobody in this institute has done geometric morphometrics before. I would be happy to get some practical hints. Thanks Louise -- Replies will be sent to the list.
