Installation of LCModel GUI

Installing LCModel in Oscar

Installing LCModel in Oscar for personal use is a simple process. Because LCModel has a graphical interface, you will need to connect to Oscar using the Desktop Application via OpenOnDemand, this will make sure we are using a node that can find its $DISPLAY.

• Click on the Desktop Icon and start a Desktop job. If you receive an error the error you are already running a Desktop session, you will need to click on "My interactive sessions" at the top panel on the page. You will see your existing session. Click Launch to start this session.

• Launch a terminal inside the Desktop interface.
