If there are no international students the lectures are given in Czech language only. The course is focused on some of the methods of geometric morphometrics in biology.
The aim of the course is to provide the basic background to the GM methods and to use them with different relevant software packages [TPS package, R (geomorph, shapes, Momocs), PAST] by analysing different model data sets. The course should be attended after or in parallel with the lecture B120P83 "Introduction to phenetics and cladistics" and some of the courses focused on using the R software.
