Dear Morphometrics Wizards,
I have 2 questions for which I am hoping to get help on:
Question 1. CVA analysis: I have 6 sites. Within each site I have at least
22 samples. When I ran a CVA comparison on these 6 sites in Morpho J. I was
hoping to find a way to get an actual value for each of my
Hi guys,
Thanks a ton for your quick responses. Emma, the CV scores were so tempting
to use for comparison to other variables...What would you suggest would be
a more appropriate index to use in order to compare the shape ordination
results to say, environmental variables, such as sediment
Gabi,
While Michael is correct i how you can export the CV scores from MorphoJ, I
would highly recommend against exporting the CV scores to plot against
other parameters. The reason being that CVA should not be used like
Principal Components Analysis. CVA axes should be used for inspecting the
Hi Gabi,
Answer 1: After you have performed your CVA in MorphoJ there will be a
CVA... under the Project Tree tab. Click on the branch of the CVA that
has a notepad next to it (likely named CVA...,score). After it is
selected, go to File Export Dataset... You will be prompted to select
the data
Gabi,
If you are interested in the relationship between a set of shape variables
(your Procrustes coordinates) and a single variable (e.g. precipitation),
you could use a Multivariate Regression in MorphoJ, or better, a Procrustes
ANOVA (which is procD.lm() in geomorph. Not sure if the Procrustes
Thank you, Emma. I definitely wouldn't want any fairy casualties caused by
my data analyses!!!
