[MORPHMET] MorphoJ update
Dear colleagues I have just uploaded the new version 1.06d of MorphoJ to the web page: http://www.flywings.org.uk/MorphoJ_page.htm This release contains a bug fix concerning the reading of Nexus files (File Import Phylogeny File). If the file contains numbers for internal nodes, the previous versions tried to translate those numbers and insert taxon names as node labels, which could lead to crashes when mapping morphometric data onto the phylogenies. The new version handles the labels for internal nodes of the phylogeny correctly (i.e. it does not change them). Thanks to Ashley Hammond for alerting me to the problem. The new version also contains fixes for various minor but annoying bugs, including one that caused an error when mapping a single covariate onto a phylogeny. Thanks to several participants of the workshop in Els Hostalets for showing me the bugs. Another change concerns the test for hypotheses of modularity (Covariation Modularity: Evaluate Hypothesis). Previous versions reported the number and proportion of landmark partitions with RV coefficients smaller than the one for the landmark partition specified by the hypothesis of modularity. The new version reports the number and proportion of partitions with RV coefficients smaller than or equal to that of the hypothesis. This is more in keeping with conventional statistical tests. Finally, a further minor bug fix concerns the importing of covariance matrices and converting them back to the coordinate system of landmarks. If the data have object symmetry, a bug caused the symmetry properties to be incorrectly transferred. Thanks to Elis Damasceno for telling me about the problem.

[MORPHMET] MorphoJ update
Dear morphometricians I have recently uploaded the new version 1.06c of MorphoJ to the web page: http://www.flywings.org.uk/MorphoJ_page.htm This release contains an addition to the procedure for principal component analysis. The output now contains some integration statistics in addition to the standard PCA outputs (variance of eigenvalues, variance of eigenvalues scaled by the total variance, and scaled to an interval between 0 and 1). For an example of the use of this kind of integration statistics, see Gómez, J. M., F. Perfectti, and C. P. Klingenberg. 2014. The role of pollinators in the evolution of corolla shape integration in a pollination-generalist plant clade. Philosophical Transactions of the Royal Society of London B Biological Sciences 369:20130257. http://www.flywings.org.uk/PDF%20files/PhilTrRoySoc2014_Erysimum.pdf There are also a few bug fixes. The most noticeable concered importing data from TPS files. Importing data from TPS files containing records starting with LM=0 (no landmarks for an object) produced an erroneous record in the dataset. The new version of MorphoJ is issuing an error message and aborts the data import in this situation. Thanks to the participants of the Plant Morphometrics workshop in Els Hostalets de Pierola for alerting me to this bug.
