Greetings!
I am interested in the measurement of local variation in the head shape of gilthead seabream populations, particularly on the aspect of statistical properties of parts within configurations. I found that Lory software, created by Márquez et al. (2012)*, provides the tools I am seeking for, however I have difficulties when trying to replicate the steps in the manual. I hope that someone that has the experience with it can share some light on the matter that are puzzeling me: On the example data with *Drosophila* species authors have computed sample mean wing shape deformations for the two Drosophila species (Fig. 4). o How did they do that? Did they computed the group means in other programs or R packages and then imported them in Lory or there is a way to get them in Lory because I haven’t found an option to do that. One of the ways, as I see it, is to compute the mean shapes in geomorph and them import those means shapes in Lory to visualise those means shapes. After one iteration of the Delaunay algorithm, without any selection of evaluation nodes, Lory found 74 nodes for evaluation. Based on that map of interspecific differences in local wing shape (Fig.5), on the extracted Jacobian determinants (74) ANOVA with Bonferroni correction for multiple comparison was performed which resulted with significant (stars) and non-significant (crosses) differences. o How did they computed that one shape with displayed interspecific differences? o Did they extracted Jacobians determinants from Lory and then performed ANOVA in some other program? o How did they know which node was significant or not? I suppose that you have to extract the coordinates that reflect their position on the map of interspecific differences or did I get it wrong? How did they computed the mean representation of intraspecific variance in Drosophila species? In Lory or in other program? Figures 7. and 8. represent interspecific correlations and interspecific differences and intraspecific variances. I suppose that these figures were computed in Coriandis software** on Jacobian determinants? I tried to import the data in Coriandis to explore if I could compute and get those figures but I am having problems with assigning group info and names to the imported non landmark data such as Jacobian determinants – no way I could manage to do that even when I tried to follow the footsteps in the manual that authors provided. Thank you for your time and consideration. Sincerely, Igor * Márquez, EJ., Cabeen, R., Woods, RP., Houle, D. 2012. The Measurement of Local Variation in Shape.
