Dear Anneke, That's the problem. This exaggerated structure is only present in some of the species, and one of the goals is precisely to study the evolution of this structure. best, Karla On Tuesday, March 19, 2019 at 10:42:18 AM UTC-3, Anneke van Heteren wrote: > > Dear Karla Shikev, > >

Dear Karla Shikev, Have you tried digitising the tip of the pointy structure with a normal Landmark, and semi-landmarks before and after it to digitise the rest of the structure? This, of course, only works if the pointy structure is visible in all your specimens. Best wishes, Anneke van

Dear all, I've been trying to use sliding landmarks to represent the outlines of different species and then to use those data to project the shapes onto a morphospace (as in the Olsen et al. 2017). However, part of the outline involves a local pointy structure that is functionally important,
