All Implemented Interfaces:

IAtomicDescriptor, IDescriptor

@TestClass(value="org.openscience.cdk.qsar.descriptors.atomic.RDFProtonDescriptor_GSRTest")
public class RDFProtonDescriptor_GSR
extends Object
implements IAtomicDescriptor

This class calculates GDR proton descriptors used in neural networks for H1 NMR shift.

This descriptor uses these parameters:

Name	Default	Description
checkAromaticity	false	True is the aromaticity has to be checked

getDescriptorNames

@TestMethod(value="testNamesConsistency")
public String[] getDescriptorNames()

Description copied from interface: IDescriptor

Returns an array of names for each descriptor value calculated.

Many descriptors return multiple values. In general it is useful for the descriptor to indicate the names for each value.

In many cases, these names can be as simple as X1, X2, ..., XN where X is a prefix and 1, 2, ..., N are the indices. On the other hand it is also possible to return other arbitrary names, which should be documented in the Javadocs for the decsriptor (e.g., the CPSA descriptor).

Note that by default if a descriptor returns a single value (such as ALOGPDescriptor the return array will have a single element

Specified by:

getDescriptorNames in interface IDescriptor

Returns:

An array of descriptor names, equal in length to the number of descriptor calculated..
