Subject: Number of relative
warp scores
To: [email protected]
Hello all,
Currently I working on intraspecific varianz of flower shape and I am quite new to it.
I have 10 flowers with 220 landmarks (how I got them see below) each. And I used tpsRelw to calculated the relative warps (RW).
As far as I understood I should get 436 RWs (220*2 - 4), but when I save the "relative warp scores", and also in the report, I only get 9 RWs. This number seems quite low. Does anyone know why I only get 9 RWs? Or if I did a mistake?
If you need additional information please ask.
Thank you,
Jonas
How I got my landmarks:
It is a flower with 4 Petals and I have 8 Landmarks and 4 curves with 55 Semilandmarks. One "Start" and One "End" Semilandmark is the same as a Landmark.
Then I used tpsUtil to equal landmarks and semilandmarks ("append tps Curve to landmarks") and delete the Semilandmarks which are overlapping with Landmarks (tpsUtil: "Delete/reorder landmarks").
So I have 220 landmarks. So I created a "sliders file" for tpsRelw
And I calculated the relative warps with tpsRelw.
