Hi Mark-
This is an issue I need to address as some point.
There is a way to handle this reasonably easily, albeit a bit untidily:
1.) Load your data file into CoordGen using the "Load TPS file (no
ruler/no scale)" option. Save the file in IMP format. The shape
coordinates will be correct, but the centroid size will not be scaled
correctly. The centroid size is the last column of the data matrix.
2.) Load your data into tpsRelwarp and save a file of the Centroid sizes
calculated in tpsRelwarp. These will the be the correctly scaled
centroid sizes of your specimens, in the same order as in the IMP format
file.
3.) Load your IMP data file and the CS file into Excel, as separate
files. Copy the CS values from tpsRelwarp into the last column of the
IMP file, replacing the incorrectly scaled CS values from CoordGen, with
the correctly scaled values from tpsRelwarp. Save this as a text file
from Excel, probably changing the name to reflect the change in the CS
values. It will now work properly in the IMP programs.

Dear morphometric colleagues,
I'm trying to load a tps file into CoordGen. Using tpsDig, I chose 17
landmarks as well as using the "Set Scale" option to establish size on
each specimin. I'm not sure now which option to choose for the file
format to import this into CoordGen. If I choose "Load TPS file (with
ruler)" it assumes 2 of my 17 landmarks are the ruler, so this is not
correct. But then the other TPS option, "Load TPS (no ruler/no scale
factor)" doesn't seem to be correct either. In this option does "no
scale factor" mean that the data has been correctly scaled OR NOT? Is
there an option that allows me to utilize my TPS file in its current
format or must I go back and add 2 additional landmarks to establish a
"ruler"? Thanks for the assistance!
