Hi all, I'm trying to use the unbending tool in tpsUtil, and after reading the help of that program I realized I'll need a nts file that contains the LM for the quadratic curve. But I'm not sure how do I get/create this kind of file. Is it something I can create from my tps file using tpsUtil (or any other program of that package)? I tried converting tps to nts - is this the way? or maybe I can just edit a text file and eventually change its extension to nts (as tps files can be read by notepad)? if yes, what is the exact format I should make it?
Another, though more theoretic question: what are the guidelines or what cases are suitable for using the unbending tool? I digitized extra semi-LM's along a pigment on my tadpoles, starting at the tail tip and ending at the eye. The pigment curve changes according to the body posture (the curve is composed of 7 semi-LM's) so my idea was to unbend the body according to the pigment after the pigment is straighten. Is it possible to use the unbending tool like that? if not, can I unbend it using the pigment in R (any of the GMM packages or else)? How exactly does the unbending tool works: does it unbend fixed and semi LM according to the distance beween the pigment curve and a straight line that goes through all pigment curve semi-LM's? I'm not sure I got this.
