Description

Descriptor that Characterizing Molecular Complexity in Terms of Carbon Hybridization States

Usage

1
extractDrugHybridizationRatio(molecules, silent = TRUE)

Arguments

molecules

Parsed molucule object.

silent

Logical. Whether the calculating process should be shown or not, default is TRUE.

Details

This descriptor calculates the fraction of sp3 carbons to sp2 carbons. Note that it only considers carbon atoms and rather than use a simple ratio it reports the value of Nsp3/(Nsp3 + Nsp2). The original form of the descriptor (i.e., simple ratio) has been used to characterize molecular complexity, especially in the are of natural products, which usually have a high value of the sp3 to sp2 ratio.

Value

A data frame, each row represents one of the molecules, each column represents one feature. This function returns one column named HybRatio.
