I don't personally know of any software where you can analyze open
curves in 3D, but it sounds like your analysis could be done in 2D since
the x and y coordinates are the only things varying along the midline of
a symmetric organism.
What kind of outline analysis are you doing? If it's sliding landmarks
(which might be a good idea considering you can calibrate homologous
points at sutures), tpsdig, tpsutil, and perhaps tpsrelw should do the
trick. Eigenshape analysis can also examine open curves. And since you
can calibrate certain points, if you opt to do this method an extended
shape distribution as opposed to a standard shape distribution would be
more precise. I haven't done eigenshapes myself, so I don't know what
software to recommend.

Hi All,
I would like to compare the profiles of 3D curves. These curves are
actually the midline profiles from the skulls of various mice. The
ultimate goal is to see whether there is any significant difference in
the curvature of the nasal bone or the height of the nasal bridge.
The outline softwares I have seen so far wants the curves to be closed.
Unfortunately these are open curves.
Does anyone have a tool/method suggestion?
Thanks,
M
