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) this, careful validation is required. Coot provides a range of validation tools, listed below. Having built an initial model, it is usual to check all of these and reconsider any parts of the model which are highlighted as problematic before deposition of the atomic coordinates with a public database. Coot is built upon a number of libraries. Crystallographic tools include the Clipper library for manipulating electron density and providing crystallographic algorithms, and the MMDB for the manipulation of atomic models. Other dependencies include FFTW, and the GNU Scientific Library. Much of the program's functionality is available through a scripting interface,
