Dear morphometricians
I just have uploaded a new release of MorphoJ: version 1.05a, which
includes a new method and several bug fixes.
This version includes a new method: the command Compare Vector
Directions in the Comparison menu peforms angular comparisons between
vectors in shape space that result from multivariate analyses such as
principal components, regression vectors, partial least-squares axes
etc. The procedure provides the angles as well as P-values for the null
hypothesis that the angles are no more similar than angles between
random vectors drawn from a uniform distribution on a hypershere with
the appropriate dimensionality.
See:

The new version includes a bug fix for PLS analyses within a single
configuration. For these analyses, if they were derived from a
covariance matrix (rather than from a dataset), there was a bug in the
routine reading information from a stored project file (with "Save
Project" or "Save Projet As", and then "Open Project" or "Open Recent
Project"). The bug affects the updating of the analyses and, for pooled
within-group analyses, the displaying of the results. The bug us now
fixed, but users should re-run within-configuration PLS analyses derived
from covariance matrices and delete the old versions of those analyses
from their projects (otherwise, the error persists in the old analyses).
Thanks to Chuck Kimmel for alerting me to this bug!
The new version also can handle row and column labels in the files when
importing covariance matrices.
Another minor bug was fixed, which produced a failure in drawing
histograms if all values were the same (e.g. all zero). Thanks to José
Tavera for reporting the problem.
Best wishes,
Chris
