 After you login, you will see a pop-up window that will ask you which AMs you would like to interact with in this session. First of all unclick the All/None checkbox to uncheck all the AMs. Then make sure that you only check '''bbn-pgeni.cm''' and '''utahemulab.cm''', note that there are AMs with similar names make sure you choose these two.

 Now Flack will go behind the scenes and invoke listresources in the selected AMs and populate the map. While Flack is loading the resources you can browse through your personal information by clicking to the button with your username on the left. You will see your credential, your certificate and your ssh keys.

 While Flack is loading the resources let's understand how the same functionality works with Omni. Omni is configured through a text file that is called omni_config. Go back to the terminal window and go under the directory that corresponds to your user

+Now you can switch back to the browser and look at the map of resources. Arguably this is a match better representation of the resources than the text file given back by Omni. 
+Under your username on the left there is a button called createslice. This is how you can create new slices in Flack. Create a new slice called "sliceflack##" based on your username. 
+For example gpousr25 should create a slice called "sliceflack25". An empty canvas should open up and under your username there should be at least this new slice. 
+
+=== Createslice and listmyslice in Omni ===
+In order to do the same thing in Omni, you have to invoke the createslice command. Switch to your terminal window and type 
+{{{
+omni.py createslice sliceomni##
+}}}
+For example user gpousr25 should type :
+{{{

+
+In order to see your active slices with Omni, you will have to use the `listmyslices` command. 
+{{{
+omni.py listmyslices gpousr##
+}}}
+
+For user gpousr25, this would look like :
+{{{
+geni@geni-vm:~/Tutorials/ExptWorkflow/gpousr25$ omni.py listmyslices gpousr25

+Notice how you can see the slice that you created with Flack from Omni as well. If you go back to flack and click the reload button that is next to the Slice under your username on the left you will see that the Omni slice will appear there as well.
