Dear
Andrea,
I have a similar problem in combining 2 datasets.
Do you mean by combining the shape variables in xls that you combine the
landmark coordinates from 1 individual in the first dataset with the landmark
coordinates of that same individual in the second dataset, creating 1 dataset
with 2 columns of landmark coordinates? In that case there should be at least 1
landmark that is present in both dataset as a link, right? The Adams (1999)
paper mentions including also the ratio of size of the 2 datasets i.e. centroid
size when using the separate subset method. How should you include this in the
compiled xls?
Thanks in advance.
Kind
regards,
Pepijn Kamminga

Dear Wendy,
There's a good chance that you may find the
answer to your question in this paper:
http://www.public.iastate.edu/~dcadams/PDFPubs/1999-Adams-EER.pdf
I have the suspicion that in your case appending
the shape variables might be the option. Easy to
do in xls etc. The appended matrices will
probably have to be analysed in another software
(PAST, R or any commercial stats soft.). The
visualization will have to be done for each
separate structure, however, if you use this method.
Linking in MorphoJ, as far as I know, has a
different meaning and it is in the context of the
PLS or similar analyses (for instance, if I aim
to measure the covariation between the mandible
and cranium, that might be the analysis). If
that's you purpose, it's even easier (doable in
MorphoJ, TPSPLS and probably PAST).
Cheers
