Attributes (e.g. short, long). Derived data: ratios, percentages, indices, transformations, etc. This course is entitled to teach the main concepts of shape analysis based on landmark coordinates and its multivariate procedures, and how they can be put into practice across any biological discipline in which the phenotype (form) and its variation are the principal sources of information.

This chapter covers three principle morphometric methods, that will be called voxel- base deformation-based and tensor-based morphometry.

Deformation- based morphometry (DBM) is a method for identifying macroscopic anatomical differences among the brains of different populations of subjects. Leaf morphometrics are used frequently by several disciplines, including taxonomists, systematists, developmental biologists, morphologists, agronomists, and plant breeders to name just a few. Leaf shape is highly variable and can be used for identifying species or genotypes, developmental patterning within and among .

However, very few studies have tried to assess the impact of sampling error on analytical. Information on the biology and population structure of any species is a prerequisite for developing management and conservation strategies.
