Description

Descriptor of Topological Polar Surface Area Based on Fragment Contributions (TPSA)

Usage

extractDrugTPSA(molecules, silent = TRUE)

Arguments

molecules

Parsed molucule object.

silent

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

Value

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

Details

Calculate the descriptor of topological polar surface area based on fragment contributions (TPSA).
