I agree with these comments but would like to add another point. I prefer to
think that the purpose of the PCA is to produce a low-dimension space that
captures as much of the overall variation (in a least-squares sense) as
possible. Within that space there is no need to limit the
Dear David,
Great question! I disagree with the statement that the samples' variance
in shape space is not biologically real or, perhaps more accurately, is
less real than the variance in any other space. As far as I see it, the
basic strategy in any biostatistical study, be it GM or otherwise,
Gabriel,
TPS files are regular text files with data structured in a certain way.
Just open your TPS file in a plain text editor (Notepad++ is a good choice)
and fix the paths manually using the regular search-and-replace facility.
Hope this helps.
Salud!

Hi Grace,
I provided a general overview of freely available software for geometric
morphometric analyses in a recent publication (

The paper focuses on
Hi everybody,
I'm doing geometric-morphometric on fish pictures. With TPSutil, I built my tps
files from images and I digitalized landmarks. I let the 'include path' option
checked for all my TPS files.
Now I want to save a back up of those images with their landmarks.
Unfortunately, I'm
Good afternoon all, I have a question about interpretation of PCs. I have
come across several articles in orthodontic literature having to do with
morphometric analysis of sagittal cephalograms that discuss warping a
Procrustes analysis along a principal component axis. Essentially the
Hello everyone,
For my master thesis I look at sexual dimorphism of the zygomatic. I want
to do an analysis a PCA and DFA with size included. I found that I can do
the PCA with size in morphologika, but morphologika cannot do the DFA. In
MorphoJ I cannot find an option to let size be
