This “model” provides a count of the number of heavy atoms (i.e. not hydrogen) in a molecule. While labelled “model” this calculation is merely a simple property, but when installed will appear in StarDrop in the “Models” tab alongside the ADME QSAR models and other simple properties as a “Custom model”, allowing it to be calculated easily for any data set.
