That will work but you could also just use tpsDig and mark both
landmarks and semilandmarks using the landmark tool. All that tool does
is to record the x,y-coordinates of points. It is only when you prepare
the 'sliders' file (perhaps using tpsUtil) that you indicate the
distinction between which points are fixed landmarks and which points
are allowed to slide between which other points. The only advantage of
using the curve tool is that it shows points connected so that it looks
like you are drawing an outline.
Notice that the name of the tool is "background curve". It was not
originally intended for the collection of points to be actually used in
the computation.

Dear Dustin,
I had somewhat similar kind of question.I used sliding semilandmark method to
capture the snout shape in frog.
You can try selecting the landmark along a curve in TpsDIG and then change
those landmarks into sliding semilandamrks in TPSutil.
I think this way you can be able to capture the outline.
Correct me if i am wrong.
Regards,
Kalpana

I am an undergraduate researcher looking to describe differences in
head shape among male and female salamanders. I have been using
tpsDig, but have had no success with the outline function. I would
ideally like to outline the entire head and have a set number of
landmarks digitally placed along the curve.
