 === To actually use jupyter ===
-Repeat these steps:
+First, inside a minerva terminal, launch the jupyter server, and keep it running:
-  * In *one* terminal, lauch the jupyter server on minerva, and keep it running:
-  ssh minerva01
+   ssh minerva01
-  module purge; . /home/SPACK2019/share/spack/setup-env.sh; spack load libpng
+   source python37_venv/bin/activate
-  source python37_venv/bin/activate
+   jupyter lab --no-browser --port xxxx   # <-- prints connection info
-  jupyter lab --no-browser --port xxxx
+Ideally, you launch `jupyter` inside a `screen` session, which you keep running indefinitely, independent of disconnections.
 Starting the jupyter server will print some text with info how to connect.  You will need this text soon.
-  * In *another* terminal, activate the ssh-tunnel with port-forwarding:  ''ssh minerva01_jupyter''.  Leave this connection open!
+Second, in activate the ssh-tunnel with port-forwarding by ssh-ing into the 'tunneled' connection:
-  * In a web-browser on your laptop, go to the web-page mentioned in the first bullet.
+  ssh minerva01_jupyter
+Leave this connection open, while you're working in Jupyter,
+Finally, in your local web-browser on your laptop, go to the web-page mentioned in the first bullet, i.e. something like `http://localhost:xxxx/lab?token=279f72788d79160801ab9cd2d9485e3d073bc05a78db9e37`
+where the 'xxxx' is the port-number you have chosen.
 ====== Running Jupyter on Minerva (2019) =====

 It is possible to run a Jupyter server on Minerva, and to display the notebooks locally on your laptop/desktop.
-First, make sure you have access to ''jupyter notebook'' on Minerva.  Harald followed [[minerva:lalsuite|Installing LALSuite on Minerva (the SPACK way)]] until he had a (personal) environment inside which he installed (his personal copy of) ''jupyter notebook'' via ''pip install''.  Alternatively, Steffen says that ''spack'' also has a jupyter package, which may avoid the need to setup one's own environment and ''pip install'''s.
