Right click on the visualization window and set the scale factor to the PC
score you want to visualize.
By default, it's 0.1 (if I remember well). That means that you see the
shape corresponding to a specimen with a 0.1 score on that PC. However,
your actual largest value might be 0.05 and that means that the
visualization magnifies twice the shape change for the most extreme
specimen on that PC. Set it to 0.05 if you don't want the magnification and
to minus whatever the most negative score is on that PC to show the
opposite extreme.
Be careful not to 'overinterpret' superimposed shapes. You can see Fig. 9
of Viscosi & Cardini, 2011, Plos One, to see why that could be tricky.
Good luck.
Cheers
Andrea

Hi morphometricians!
I have done PCA in Morphoj and imported an outline file to better
visualize the shape variation. The drawings of each PC worked but I'm
not sure what the best way would be to show the extremes for each PC in
each axis. The PC graphic results show two reconstructions, one which
appears to be a mean reconstruction in light blue and a dark blue
reconstruction which looks like one of the extremes in a PC. Is this the
most positive value for that PC? If so, how would I get the most
negative reconstruction?
Thanks in advance!

Daniel,
You cannot change the shape of the dots directly in MorphoJ. However you
can easily export the file as a vector graphic (.svg) and change
anything you like about it in Inkscape or Adobe Illustrator.
Hope that helps.
Emma

Dear Morphmetricians,
I am currently using MorphoJ to analyze my dataset. My dietary groups
are color coded but I need them coded by shape (triangle, square,
circle) so that I can print out my graphs in black and white. Can this
be done in MorphoJ or is there another shape analysis software that
allows for this?
Thank you,
Daniel Arrañaga
