I have uploaded ver. 1.78 of tpsUtil to the http://life.bio.sunysb.edu/morph
website.
It just fixes an internal exception error when one completes the "unbending"
option (after the output file was saved). Thanks to Gabriel Gazzana Barros
for reporting the problem.
An improved version of this type of correction (the delta-corrected K-S test
for an intrinsic null hypothesis) is discussed in the text Biometry (Sokal and
Rohlf, 4th ed. 2012) and a table Y is also provided for this test. It should
be more widely known and appreciated.

Yes, on the options menu there is an option to set the decimal charactet.

PC1 by definition corresponds to the direction of maximum variance in your
data. Within a species and sex this usually corresponds to size and/or age if
you include specimens that do vary in size. However, if you include different
species and sexes or specimens that are about the same size then
If you set the scale for the first one it will be used for all the rest.

The thing to remember is that the comparative methods adjust for the lack of
independence of the observations. Thus variables being multivariate does not
change the computation of PICs or, preferred, the use of generalized least
squares.

Actually the rule is that the number of specimens should be larger than the
number of variables 2p-4 not p landmarks in the case of 2D data.

I have just uploaded tpsUtil with a small update - version 1.76. The
area/perimeter option can now use .nts files and not just .tps file. It also
now includes a PDF file copy of the help file. Some may find that helpful.

You need to use the decimal character option in tpsRelw to select “.” Rather
than “,”.

You can only process one file at a time. If your data are in many files then
combine them using the tpsUtil program.

I have just uploaded ver. 2.05 of tpsSuper, 2.31 of tpsDig2, and 1.75 of
tpsUtil.
Main change to all three was to add additional image file formats - most
importantly camera raw images files. See the list below. This change was
suggested by Jennifer Valvo. In addition, I fixed a problem readi
Let it save it as a txt file then just rename the file.

If you set a number of points less than the digitized number of points then the
software has to interpolate and that is likely to cut off the corners. This is
especially true if the shape is irregular. No easy solution except that you can
edit the points and push them around to where you would l
