Description

Descriptor that Calculates the LogP Based on a Simple Equation Using the Number of Carbons and Hetero Atoms

Usage

1
extrDrugMannholdLogP(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 LogP based on a simple equation using the number of carbons and hetero atoms. The implemented equation was proposed in Mannhold et al.

Value

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