Exact Mass Calculator
This calculates the “exact mass” of a molecule based upon the masses of the most abundant isotopes of its substituent atoms. As such, this calculation will often be slightly different to the molecuar weight calculation which is based upon average isotopic distributions. When installed, this 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. If you’ve not used custom models before, details on how to install it are available on the following pages, along with the model file…
Installation
Save the model file (Exact mass.aim) into the StarDrop model files directory (in a default installation this will be “C:\Program Files\StarDrop\modelfiles”).
When you start StarDrop the model will appear in the list of available models.
