extrDrugAutocorrelationPolarizability(molecules, silent = TRUE)

Arguments

molecules	Parsed molucule object.
silent	Logical. Whether the calculating process should be shown or not, default is TRUE.

Details

Calculates the ATS autocorrelation descriptor, where the weight equal to the charges.

Calculates the ATS autocorrelation descriptor, where the weight equal to the scaled atomic mass.

Calculates the ATS autocorrelation descriptor using polarizability.
