Dear tpsDig users, After a time away from using tpsDig I am back digitizing Sympetrum (Medowhawk dragonfly) wings with tpsDig2 … with a twist. I am doing it on a Mac using wine, the PC emulator. It works well but I am in need of one of the old functions called template-mode.
In the 'old days', template mode allowed you to use an empty tps list of image file names with LM set to zero to acquire a first set of landmarks on specimen 1 and then inherit those landmarks to specimen 2 and then in an edit step take one of the extreme landmarks and move it to its correct location on specimen 2 with all the other landmarks following in parallel. Then on had the opportunity to pick up another extreme landmark and move it to its correct location … all the while the other landmarks were scaled to fall at their calculated positions in between … relatively close to where they should be in a similar or identical species. This was a very valuable tool for inheriting the general locations of landmarks on 2-D specimens such as my hundreds of Sympetrum wings. Now, as I am using the template mode of tpsDig2 most recent version, I see that the new inheritance mode works differently and I want to be sure that I can use it most effectively. I now, after digitizing my first specimen in the tps list, put on template mode and go to my next image. I then grab a central, rather than an extreme landmark and move it to its correct location on the image. Once I then release it all the other inherited landmarks have been moved in parallel to new locations somewhat near their correct locations but would benefit from rotation or isometric scaling to be closer to their correct locations on the image. I then have the sometimes laborious task of moving the landmarks to their correct positions and when they need substantial rotation or resizing the task is more laborious than in the old days when the resizing and rotation were a part of the inheritance protocol. … Am I missing some widget or control-key the would allow better inheritance of the landmark positions. Perhaps in using wine I have lost some help file that would have told me how to use the new inheritance tool. It still is the best 2-D digitizing software, is it not?
