Dear Joanna,
this is something you can easily check: compare a PCA, shape distances and
also centroid size from TPSRelw with those from MorphoJ after redoing the
GPA: are they different?
If they are, I'd worry. But, unless there's a mistake, I'd say they will be
virtually identical.
Cheers

Hello All,
I was thinking about using TpsRelw to slide semilandmarks before analysing
the aligned specimens data in MorphoJ, but does it really make sense to
double the alignment?
Even if I have the file after TpsRelw, where landmarks and semilandmarks
are treated differently, im MorphoJ I make the
The point is simple: the variables called centroid size and log centroid
size in MorphoJ won't be the real size of the original structures if
they're imported without rescaling them.
They are, in my experience, about 1 and, regardless of the reason (which
I find less important), they're wrong. O
Hi folks/Andrea,
just to underline this:
Andrea,when you say
"an 'apparent size variable' which is a series of numbers virtually equal
to 1 (differences will be approximation errors)."
I think that MorphoJ "reads" the actual CS values from the aligned
coordinates saved by TPSrelw that, as you sa
Hi Pere,
there's plenty of work arounds this. I agree with Carmelo that the nts
format may be easier to edit manually, so that you can put back the
necessary labels.
HOWEVER, PLEASE BE CAREFUL because SIZE WILL BE MISSING from those data.
As most of the time you may want to analyse both size
