3D GEOMETRIC MORPHOMETRICS COURSE HAS OPENED REGISTRATION
AAPA Members have a 20 % discount on the fee!
Instructor: Lissa Tallman (Grand Valley State University, USA)
Dates: May 3rd-7th, 2021
Schedule: Online live sessions from Monday, May 3rd to Friday, 7th; 14:00 to 19:00 (GMT+2, Madrid time zone). 25 hours of online live lessons, plus 10 hours of participants working on their own. This course is equivalent to 1 ECTS (European Credit Transfer System) at the Life Science Zurich Graduate School. The recognition of ECTS by other institutions depends on each university or school.
Types of data acquisition. 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 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: – DVLR (free). – Landmark Editor (free). – MorphoJ (free). – PAST (free). – R (free, only for sliding semilandmarks, no previous knowledge is required). – Microsoft Excel.
