GetClearCoords

bool GetClearCoords() const

GetMaxBondRotations

unsigned int GetMaxBondRotations() const

• OEAlignedDepictionFrom3DOptions::SetSuppressHydrogens method

GetSuppressHydrogens

bool GetSuppressHydrogens() const

Returns whether the explicit hydrogens are suppressed in the molecule prior to generating the 2D coordinates.

SetClearCoords

void SetClearCoords(bool clearcoords)

If false and the fit molecule has 2D coordinates, then these coordinates are used for the alignment. Otherwise the 2D coordinates of the fitted molecule are generated by calling the OEPrepareDepictionFrom3D function.

SetMaxBondRotations

void SetMaxBondRotations(unsigned int maxrotations)

Sets the maximum number of bond rotations performed during the 2D coordinate generation process.

maxrotations

The zero value means that there is no limit. Upon reaching this limit, the process terminates and returns the “best” aligned 2D coordinates.

Hint

The default value for maximum number of bond rotations is \(2^{16} = 65536\). This means that by default only the first 16 single bonds of the molecule will be rotated to find the “best” aligned 2D layout.

It is recommended to use this parameter if the input 3D molecule has a large number of rotatable bonds.

SetSuppressHydrogens

void SetSuppressHydrogens(bool)

Sets whether the explicit hydrogens are suppressed in the molecule prior to generating the 2D coordinates. Only hydrogens that are necessary to faithfully represent tetrahedral stereochemistry will be kept.
