3D GEOMETRIC MORPHOMETRICS

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 MorphoJ.
– Between-group PCAs.
– PCAs in Procrustes form space.

Visualizing shape change.
– Using MorphoJ in conjunction with Landmark Editor.

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).

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

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

Programs that we will use:
– Stratovan Checkpoint (temporal licences
will be provided during the course).
– DVLR (free).
– Landmark Editor (free).
– MorphoJ (free).
– PAST (free).
– R (free, only for sliding semilandmarks, no
previous knowledge is required).
– Microsoft Excel.
