Selection of descriptors with potential modeling ability

When molecular descriptors will be used to model some molecular property (i.e., QSAR/QSPR analysis), then a preliminary variable selection can be carried out by Dragon according to the flow chart below.

To export only the molecular descriptors that have the maximal correlation with a selected property of molecules, the following operations have to be carried out: the shortcut 'Molecules' icon_load to load the molecular structure files of interest; the shortcut 'Descriptors' icon_descriptors to select and calculate molecular descriptors; the shortcut 'External variables' icon_add_variables to launch the import procedure; the shortcut 'Correlation' icon_correlation to open the window 'Correlation Analysis' and select the property of interest;
