1. Create container: ~/.local/bin/udocker create --name=imas-gui imas/gui:3.24.0-4.2.0-2.5p4-3.0.5-4.6.5
2. Run the default application (VNC server) with port mapping: ~/.local/bin/udocker run --publish 15901:5901 imas-gui
3. In another terminal, open VNC viewer, connect to localhost:15901 and use imas as the password: vncviewer localhost:15901
4. You will see Openbox desktop environment, with Kepler loading automatically (please wait until it is ready).
5. Design an example workflow like the one below, which will read pf_active IDS from shot 1 and run 1:
   
6. Run the workflow and notice that it fails due to lack of pulsefile with required content. This is because in the previous exercise you were running in the imas container, isolated from the imas-gui one.
7. You can now do one of the following:
   1. Create the pulsefile again
      1. Run in another terminal in the Gateway: ~/.local/bin/udocker run imas-gui /bin/bash
      2. Repeat step 4 from previous exercise
   2. Copy pulsefile between containers
      1. Run cp ~/.udocker/containers/imas/ROOT/home/imas/public/imasdb/test/3/0/ids_10001.* ~/.udocker/containers/imas-gui/ROOT/home/imas/public/imasdb/test/3/0/
8. Start the workflow again. The expected result:
