After a QSAR model is created, it adds one or more new properties to the "Other" category in the Molecular Property selection box in the Calculate Molecular Properties protocol. This is the way how to apply your QSAR model in Discovery Studio. A ModelDescription.html file is always created when the QSAR model is built. If you have lost track of this file, you can use the attached protocol to regenerate one. Hope it is useful to you.

How to use:
(1) Discovery Studio 2.1 is required.
(2) Download the attached protocol. Remember where you saved it.
(3) Open Discovery Studio client.
(4) In the protocol explorer panel, right click the QSAR folder and select "Import..." to import the protocol.

This protocol will appear in the QSAR collection of protocols.
