SSSRFinder

public SSSRFinder(IAtomContainer container)

Deprecated.

Constructs a SSSRFinder for a specified molecule.

Parameters:

container - the molecule to be searched for rings

Method Detail

findSSSR

public IRingSet findSSSR()

Deprecated.

Finds a Smallest Set of Smallest Rings. The returned set is not uniquely defined.

Returns:

a RingSet containing the SSSR

findEssentialRings

public IRingSet findEssentialRings()

Deprecated.

Finds the Set of Essential Rings. These rings are contained in every possible SSSR. The returned set is uniquely defined.

Returns:

a RingSet containing the Essential Rings

findRelevantRings

public IRingSet findRelevantRings()

Deprecated.

Finds the Set of Relevant Rings. These rings are contained in every possible SSSR. The returned set is uniquely defined.

Returns:

a RingSet containing the Relevant Rings

findEquivalenceClasses

public List findEquivalenceClasses()

Deprecated.

Finds the "interchangeability" equivalence classes. The interchangeability relation is described in [GLS00].

Returns:

a List of RingSets containing the rings in an equivalence class

getSSSRWeightVector

public int[] getSSSRWeightVector()

Deprecated.

Returns a vector containing the lengths of the rings in a SSSR. The vector is uniquely defined for any SSSR of a molecule.

Returns:

An int[] containing the length of the rings in a SSSR

getEquivalenceClassesSizeVector

public int[] getEquivalenceClassesSizeVector()

Deprecated.

Returns a vector containing the size of the "interchangeability" equivalence classes. The vector is uniquely defined for any SSSR of a molecule.

Returns:

An int[] containing the size of the equivalence classes in a SSSR
