Dear colleagues,


The 7th edition of the course "3D Geometric Morphometrics" has opnened 


Dates: December 11th-15th, 2017.


Instructor: Dr Melissa Tallman (Grand Valley State University, USA).


Place:  Facilities of the Institut Català de Paleontologia Miquel Crusafont,,C/ 
de l’Escola Industrial, nº 23 08201 Sabadell, Barcelona.

Registration and more info:




Types of data acquisition: Using a microscribe. Collecting CT scans & Surface 
Scans. - Demonstration of Stratovan Checkpoint.


Brief Review of Fundamentals of Morphometrics: - How to choose landmarks. - 
Generalized Procrustes Analysis. - Other types of alignment. - Thin plate 
spline warping. Processing Microscribe data. - Using DVLR to merge two views. - 
Using resample to resample a line. Using Landmark Editor to collect data on 
surfaces. - Sliding semi-landmarks (using R geomorph package).


- How to do a precision test on 3D data.


- Data exploration: PCA analyses: Using Morphologika. Using MorphoJ. 
Between-group PCAs. PCAs in Procrustes form space.


- Visualizing shape change: Using MorphoJ in conjunction with Landmark Editor. 
Making calculations and visualizing shape changes in PCA morphospace. 
Calculating PCA scores post hoc.


- Data exploration: Regressions. Visualizing change that is associated with 
size (MorphoJ). Removing change associated from size from your data (MorphoJ). 
Common allometric trajectories. Comparing vector directions. Extracting linear 
dimensions from 3D data and using them as covariates.


- Data exploration: PLS analyses. Using MorphoJ to mean center (or not). 
Visualizing shape change in Landmark editor.


- Data exploration: Phylogeny. Visualizing shape changes in MorphoJ along a 
tree. Importing covariates and visualizing shape change associated with 
taxonomy (using MorphoJ). Creating a phyomorphospace. Correcting for phylogeny 
in PCA.


- Data interpretations: Using mean configurations (PAST) and Procrustes 
distances. Minimum spanning trees. Variability within a sample (comparing 
fossil distributions to extant distributions).


- Retrodeformation.
