A *.tps file containing two- or
three-dimensional landmark data
Value
Function returns a (p x k x n) array, where p is the
number of landmark points, k is the number of landmark
dimensions (2 or 3), and n is the number of specimens.
The third dimension of this array contains names for each
specimen, which are obtained from the image names in the
*.tps file.
Details
This function reads a *.tps file containing two- or
three-dimensional landmark coordinates. Tps files are
text files in one of the standard formats for geometric
morphometrics (see Rohlf 2010). Two-dimensional
landmarks coordinates are designated by the identifier
"LM=", while three-dimensional data are designated by
"LM3=". Landmark coordinates are multiplied by their
scale factor if this is provided for all specimens. If
one or more specimens are missing the scale factor,
landmarks are treated in their original units. NOTE: all
other information present in tps files (curves, comments,
variables, radii, etc.) is ignored.
