Detailed Description

This processor provides methods for detection and assignment of aromaticity.

Aromaticity Processor

Processor method to detect aromaticity of AtomContainers. If it is called as a processor with the operator (), the RingPerceptionProcessor is called before, to calculate a ring set. It can be called explicitely with aromatize with a ringset as parameter.

Member Function Documentation

void BALL::AromaticityProcessor::aromatize	(	const vector< vector< Atom * > > &	sssr,
		AtomContainer &	ac
	)

Calculated the aromaticity of the molcule and sets the properties "IsAromatic" for aromatic atoms, and Bond::ORDER__AROMATIC for bonds which are aromatic.

Parameters:

SSSR

ring set as vector<vector<Atom*> >, (vector of rings in vector<Atom*>) after the processing this variable holds all aromatic systems, which are not necessarily single rings!

void BALL::AromaticityProcessor::aromatizeSimple

(

vector< vector< Atom * > > &

sssr

)

Method to set aromaticity with the use of simple rules. Each ring from the given SSSR set (which needs just to be a set of rings) is examined for itself. (needed for the implementation of the MMFF94 force field which does not agree with the advanced araomtaticity definition of the default method.).

It does not set any aromaticity flags, neither at the atoms nor bonds to bond order aromatic! sssr is the set to be examined, only aromatic rings will stay

bool BALL::AromaticityProcessor::overwrite_bond_orders_ [private]

Should we set the bond orders to aromatic or merely store the information as a property of the bond? This value depends on the value of the option OVERWRITE_BOND_ORDERS
