American coot old. The American coot is a migratory bird that occupies most of North America. It lives in the Pacific and southwestern United States and Mexico year-round and occupies more northeastern regions during the summer breeding season. In the winter they can be found as far south as Panama. Coots generally build floating nests and lay 8–12 eggs per clutch. Females and males have similar appearances, but they can be distinguished during aggressive displays by the larger ruff (head plumage) on the male. American coots eat primarily algae and other aquatic plants but also animals (both vertebrates and invertebrates) when available.
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,
