13 -You can also directly jump to e.g. the [[single neuron notebook>>https://lab.jsc.ebrains.eu/hub/user-redirect/git-pull?repo=https%3A%2F%2Fgithub.com%2Felectronicvisions%2Fbrainscales2-demos.git&urlpath=lab%2Ftree%2Fbrainscales2-demos.git%2Fts_00-single_neuron.ipynb&branch=jupyter-notebooks]] or the [[learning with superspike notebook>>https://lab.jsc.ebrains.eu/hub/user-redirect/git-pull?repo=https%3A%2F%2Fgithub.com%2Felectronicvisions%2Fbrainscales2-demos.git&urlpath=lab%2Ftree%2Fbrainscales2-demos.git%2Fts_01-superspike.ipynb&branch=jupyter-notebooks]].

14 14  To run the notebook cells use the "Run" menu item. To execute all cells of the notebook use the "Run > Run all" menu item in the Jupyter window.
15 -\\Additional info: the link above clones the '//stable// version code' (for the current 'stable kernel' version). The "//stable//" version is a software set, which is updated around twice per year, so it does not have all the newest features - and not all the latest bugs.
16 -There is also an "//experimental//" kernel for the notebooks, which  is updated around weekly and has the latest improvements (and bugs). To use the "//experimental//" version for your tests, please access [[this URL to clone the **"experimental" version**>>https://lab.jsc.ebrains.eu/hub/user-redirect/git-pull?repo=https%3A%2F%2Fgithub.com%2Felectronicvisions%2Fbrainscales2-demos.git&urlpath=lab%2Ftree%2Fbrainscales2-demos.git%2Ftutorial.ipynb&branch=jupyter-notebooks-experimental]].
17 -Note: "stable" and "experimental" do not mix, as the code is different. You can restart your Jupyter session ([[how to do it>>doc:.Lab restart.WebHome]]) to get rid of the cloned files if you would like to switch the branch from stable to experimental (or vice versa) or if you just want to start fresh again.

20 -This automatically clones an example notebook for running a "synfire chain" on SpiNNaker ([[from github>>https://github.com/SpiNNakerManchester]]) into a lab session into a //non-persistent// location and opens it.

26 -* a "lab session" will be automatically terminated after some hours of inactivity. At that event the notebooks cloned via the access URL above will be deleted = any changes you entered will be lost = great for a quick "first look", but not so great for longer term research ...
