Dear morphometricians
I have just uploaded the new version 1.06a of MorphoJ to the web site.
As usual, the program can be downloaded from the MorphoJ web page:
http://www.flywings.org.uk/MorphoJ_page.htm
This version contains one new command and a series of bug fixes
(accumulated over a rather long time, I must admit).
I've also made a number of edits to the User's Guide:
http://www.flywings.org.uk/MorphoJ_guide/frameset.htm?index.htm
(These changes are also included in the offline version that is included
with the program.)
This release includes a new command for computing principal component
scores using a dataset different from the one that may have been used to
compute the principal components (PC Scores From Other PCA in the
Variation menu). For instance, this can be used for between-group PCA,
where the scores are computed for individual specimens, but the PCA is
using the covariance matrix among the group means. It can also be used
for phylogenetic PCA, where the PCA is run on the covariance matrix of
independent contrasts (or a covariance matrix from a PGLS analysis that
is imported into MorphoJ) and the scores are then computed for the
terminal taxa of the phylogenetic tree. Other applications can be
imagined too.
This version contains bug fixes for various analyses (CVA and others)
using shape change vectors imported from outside MorphoJ (imported into
the project by using Import Shape Change Vectors in the File menu). The
new version also allows users to include or exclude observations from
datasets containing shape change vectors. I came across these problems
while doing analyses of data with complex symmetries.
The new release includes a fix for a particularly hard-to-find bug,
which could produce crashes when saving a project, but only in rather
particular circumstances. I finally found the bug after Hugo Benitez,
Raffaella Bravi and the participants of the morphometrics course at Roma
Tre university pointed it out to me and I was affected by it myself.
An additional minor bug fix concerns the display of graphs for matrix
correlation if the graphs are invoked from a ved project. Thanks to
Helmi Mohd Hadi Pritam for alerting me to the bug.
The release also contains a change in canonical variate analysis. Thanks
to Benedikt Hallgrímsson for pointing out the problem to me.
Best wishes,
Chris
