Subject: Using tps-software: Request about quantification of wing forms
in birds

Hello everyone,
within the framework of my diploma thesis I need to use F. James Rohlf´s
tps-software to identify the wing shape of Northern Wheatears (a small
passerine long-distance migrant). I´ve already startet to digitalize my
wing fotos and created landmarks on the wingtips. Now I have some
problems to continue. I have used CoordGen to save the file as
Bookstein´s Superimposition and also standardized the semilandmarks by
mirroring the wing coordiantes axially-symmetrically. But I don´t really
get why to do so?
After saving the file as Procrustes (tps-format) in CoordGen, I now have
to create a slider file to generate the semilandmarks. Here I got stuck!
When trying to open the Procrustes-tps-file in tpsUtil, I always fail.
What i did: Operation --> Make sliders file
Input --> appropriate file (see attached)
Output --> selected output file
There must be something wrong, because "tpsUtil" says: "Wrong fromat,
perhaps this is a tps file?" Well, it is actually a nts file.
The next step would be to use tpsRelw to move the semilandmarks.
I hope anyone can solve these problems with the software so that I can
continue determining wing morphology with this great method as soon as
possible.
Thanks a lot.
Best Wishes,
Anna
