Create a File for the Curve Semi-landmarks

Geomorph has a function define.sliders() that can be used to create a file for the curve semi-landmarks, however it is not the easiest to use.

-Instead, use it to visualize the landmarks and find the beginning and end of the curves

define.sliders(Morton####_fixed_curve_landmarks.txt, nsliders = 20) 

- open up a spreadsheet in excel
-in the first row, write before, slide, after in the first three columns
- find the first landmark of the first curve
- type the first landmark in the first column, the 2nd landmark in the second, and the 3rd landmark in the third
- the the 2nd landmark in the first column. 3rd in the second, and 4th in the third
- and so on until the last landmark of the curve is in the third column
- save as a .csv file
