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.

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 -- A.
