Libcootapi’s Documentation

Libcootapi is a new (as of 2022) interface to the functionality of Coot. It is designed to be (is intended to be) a clean, consistent and easy-to-use interface primarily targeting WebAssembly/JavaScript and secondarily, Python.

The previous API for Coot still exists and is available for use with Python and Guile/Scheme (it provides the coot module). That interface is considerably more extensive than this one (consisting of several thousand API functions), but is significantly less easy to use as it embeds OpenGL and GTK libraries (and all of their dependencies, of course).

The Molecules Container

Coot’s molecules are referred to by index and should only be accessed via member functions of the molecules_container_t class.

The functions in this class for the most part return simple types. There are some functions that return a more complex type, such as coot::simple_mesh_t or coot::validation_information_t.

Note: The private types, functions, attributes and members are listed here, but they are not, for the most part, useful for exporting. Which is not to rule out that there may be something there that could usefully be declared as public.

Get the bonds mesh

Parameters:

mode – is “COLOUR-BY-CHAIN-AND-DICTIONARY”, “CA+LIGANDS” or “VDW-BALLS”
against_a_dark_background – allows the bond colours to be relevant for the background. When the background is dark, the colours should (as a rule) be bright and pastelly. When the background is light/white, the colour are darker and more saturated.
smoothness_factor – controls the number of triangles used to make the bond cylinders and spheres for the atoms - it rises in powers of 4. 1 is the smallest smoothness_factor, 2 looks nice and 3 is best.
bond_width – is the bond width in Angstroms. 0.12 is a reasonable default value.
atom_radius_to_bond_width_ratio – allows the representation of “ball and stick”. To do so use a value between 1.5 and 3.0. The ratio for “liquorice” representation is 1.0.

smoothness_factor – controls the number of triangles used to make the bond cylinders and spheres for the atoms - it rises in powers of 4. 1 is the smallest smoothness_factor, 2 looks nice and 3 is best. Instancing may mean that smoothness factor 3 should be used by default.
bond_width – is the bond width in Angstroms. 0.12 is a reasonable default value.
atom_radius_to_bond_width_ratio – allows the representation of “ball and stick”. To do so use a value between 1.5 and 3.0. The ratio for “liquorice” representation is 1.0.

Go to Blob

std::pair<bool, clipper::Coord_orth> go_to_blob(float x1, float y1, float z1, float x2, float y2, float z2, float contour_level)

Given a point on the front clipping plane (x1, y1, z1) and a point on the back clipping plane (x2, y2, z2) this function searches imol_refinement_map (if set) to find a the centre of a blob above the contour level.
