Dear Morphometrists
I am a bigginer in Geometric Morphometrics and I would be really
appreciate it if you could help me on my problem.
1) How could we calculate the Splines for tow favorite relative warp and
for mean of each population? In softwares sucj "tpsSplin" and "PAST", I
can obtain the deformation grid for each specimen (not each population)
and for each partial warp or the complete warp. But in papers I have
seen that the scatter plot of 2 relative warps (for example Rw1 and RW2)
is given asoociated with the splines for these two relative warps. How
could we estimate these splines (I mean the mean spline for tow favorite
RWs not for each one seperately).
2) What's the use and interpretation of Uniform components? I know it
shows the unlocalizable transformations, but how we could interpret it.
I was done a Cononical discriminant function analysis on 2 uniform
components but it shows really different results than CDF analysis of
aligned specimens matrix. Some groups it shows 0% correctly
classification and they calssify 100% with another groups, however CDF
analysis on aligned specimens shows really different results.
Many thanks in advance for any help
Sincerely yours
