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:

1.	click the shortcut 'Molecules'  to load the molecular structure files of interest;

2.	click the shortcut 'Descriptors'  to select and calculate molecular descriptors;

3.	click the shortcut 'External variables'  to launch the import procedure;

4.	click the shortcut 'Correlation'  to open the window 'Correlation Analysis' and select the property of interest;
