Re: [MORPHMET] Looking for suggestions on burnt bones experiment

If you have bone shapes before the heat traeatment you can use original images as "target" and depict warped zones and deformation patterns by thin plate splines. I m not sure, but if you hope that observed deformation is similar between the same kind of bone, you could build a regression model wit

Re: [MORPHMET] Elliptic Fourier analysis using PAST 3.05

Open the coordinate file in Past, then peform elliptic fourier analyses, then copy the ouput file with the harmonics (you can select the desired numer of harmonics if you want). Then open a new past window and paste the harmonics. With the desired number of harmonics you can perform now the pca usi

Re: [MORPHMET] question Elliptic Fourier Descriptors

If you want to use "free size effect data" I think it can be good idea use the residuals of the regression between the PC and log(lengh), because this residuals are new variables not explained by size. best M 2015-10-26 9:42 GMT-03:00 Jens De meyer : > Dear

[MORPHMET] question about raw tps files in R

Hi, I noted that R command redland.tps (of geomorph package) change raw tps files while open it, (scaling?). I don´t have a clear idea about how and why the program do it..please someone have an idea about it? thank in advance! M -- Dr.Mar

[MORPHMET] question about form space

Dear Colleagues, I´m interested to work in the form space (shape plus size) with the ouput data of the tpsrewl. Should I use the scale aligned specimen matrix.?, also which is the proper method to display this matrix (a PCA with the covariance matrix maybe) ?. best!
