90% of dims.
Does anyone have an idea where this problem is coming from and how to fix
it? Note that the model opens without difficulty as a binary ply in
Geomagic.
Thanks.

s of these triplets are 0,0,1 (or maybe
1,0,0).
This is really strange behavior. A read function shouldn't write.
My issue may be better suited to an R forum, but I am hoping someone here
has reliable code for reading Avizo landmarks into R.
Thanks in advance.

Hi Giada,
The object may simply be too small. However...
1. My recollection is that you need to keep your f-stop much lower, maybe
f-11 maximum. Look into it. It's possible this has changed with recent
software updates.
2. I assume each chunk is a rotation around the skull. Try shooting more

Elahe and Ari,
If your dependent observations have more than a few dimensions, such as is
typical with landmark data or even a collections of linear measurements,
then I think the common covariance matrix recommendation from Dr. Rohlf is
the more standard approach. A typical strategy for removing
shape and form.

I hope you find it interesting.

I think this does it (but please check; I quickly stuck together two
different pieces of code)...
# matrix where each vector is a row
vec.mat <- ...
#Compute group*loci matrix of mean microsatellite lengths
angle.mat <- matrix(NA,nrow=nrow(vec.mat),ncol=nrow(vec.mat))

I read Christy's question a little differently, and requiring some
clarification.
First, Dean, doesn't Dean & Felice fix the angle between jaw and cranium so
that you can subject a craniomandibular dataset to a common GPA, which at
the PLS step has the benefit of preserving relative size relations

Now if only archaeological and museum skeletal samples would stop
disarticulating and stay in anatomical position.
