Functions

angles_to_sincos(tor_angles)	Convert angles to sine and cosine values.
getDistogram(residues, atom_pos, atom_mask)	Calculates the pairwise distance matrix for atom positions.
getTorsion_acc(target_residues, tor_masks, ...)	Calculates the accuracy of torsion angles by comparing native angles with target angles and optional alternative angles.
get_bondangle(p)	Calculate the bond angle formed by three points.
get_coordinates(final_residue, residues, chain)	Retrieves the coordinates of atoms from the residues in a chain.
get_refer_atoms(restype, angletype)	Get reference atom indices based on residue type and angle type.
get_torsion(atom_mask, atom_pos, residues[, ...])	Computes the torsion angles for a set of residues.
new_dihedral(p)	Calculate the dihedral angle between four points.
readPDB(pdb_path)	Reads a PDB file and extracts residue information.
restype_refer_atoms(restype)	Get reference atom indices for a given residue type.
sidechain_sym_angle(target_residues, ...)	Adjusts the target angles of sidechain torsions based on their differences with native angles and alternative angles.
torsion_angle_loss(a, a_gt, tor_masks)	Computes the loss for torsion angles based on the difference between predicted angles and ground truth angles, including penalties for angle normalization.
