Giant coot coot, the giant coot is monogamous and the pair builds a huge nest in a highland lake. However, unlike the horned coot, the nest of the giant coot is primarily made of aquatic vegetation and – as it is fiercely territorial – it never forms colonies. Giant coot The giant coot ("Fulica gigantea") is a species of coot from South America. It is found at lakes in the altiplano from central Peru, through western Bolivia, to north-eastern Chile and extreme north-western Argentina. With a total length of 48–64 cm (19–25 in), it is the second largest extant member of the
Coot (software) Coot (software) The program Coot (Crystallographic Object-Oriented Toolkit) is used to display and manipulate atomic models of macromolecules, typically of proteins or nucleic acids, using 3D computer graphics. It is primarily focused on building and validation of atomic models into three-dimensional electron density maps obtained by X-ray crystallography methods, although it has also been applied to data from electron microscopy. Coot displays electron density maps and atomic models and allows model manipulations such as idealization, real space refinement, manual rotation/translation, rigid-body fitting, ligand search, solvation, mutations, rotamers, and Ramachandran idealization. The software is designed to be easy-to-learn for novice users,
