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.

class molecules_container_t
#include <molecules-container.hh>

the container of molecules. The class for all libcootapi functions.

void set_draw_missing_residue_loops(bool state)

By default missing loops are drawn. This function allows missing loops to not be drawn. Sometimes that can clarify the representation. This is a lightweight function that sets a flag that is used by subsequent calls to get_bonds_mesh().

coot::simple_mesh_t get_bonds_mesh(int imol, const std::string &mode, bool against_a_dark_background, float bond_width, float atom_radius_to_bond_width_ratio, int smoothness_factor)

get the bonds mesh.

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 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 (but maybe is slower to transfer) 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 (say) 1.5 and 3.0. The ratio for “liquorice” representation is 1.0 (of course).

Returns

a coot::simple_mesh_t

coot::instanced_mesh_t get_bonds_mesh_instanced(int imol, const std::string &mode, bool against_a_dark_background, float bond_width, float atom_radius_to_bond_width_ratio, int smoothness_factor)

get the instanced bonds mesh.

The arguments are as above:

mode is “COLOUR-BY-CHAIN-AND-DICTIONARY” - more modes to follow

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 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. 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 (say) 1.5 and 3.0. The ratio for “liquorice” representation is 1.0 (of course). 1.7 or 1.8 looks nice.

Returns

a coot::instanced_mesh_t

coot::instanced_mesh_t get_bonds_mesh_for_selection_instanced(int imol, const std::string &atom_selection_cid, const std::string &mode, bool against_a_dark_background, float bond_width, float atom_radius_to_bond_width_ratio, int smoothness_factor)

int refine_direct(int imol, std::vector<mmdb::Residue*> rv, const std::string &alt_loc, int n_cycles)

Real space refinement.

the n_cycles parameter allows partial refinement - so for an animated representation one would call this with a small number (10, 20, 100?) and call it again if the refine status is still yet to reach completion GSL_CONTINUE (-2). And then make a call to get the bonds mesh (or other molecular representation). If n_cycles is negative, this means “refine to completion.”
