In order to go through this tutorial you need to have access to a Unix/Linux machine, where you can run Unix terminals.
+
=== Machine setup and Training material ===
Software-wise, one needs the following:
+
* [[Getting Started#Machine setup| Machine setup]]
* One '''quantum engine''', i.e. a software able to run quantum mechanical DFT simulations. Here we consider [http://www.quantum-espresso.org Quantum ESPRESSO] (QE). During this class we'll be using QE-v6.5, though any version newer that 6.0 would do.
+
* [[Getting Started#Training material| Training material]]
* '''Structure visualization and builders''': applications like [http://www.xcrysden.org XcrySDen] or [https://jp-minerals.org/vesta/en/ VESTA](QE compatible structure visualization) and [https://avogadro.cc Avogadro] (molecular editor) will be used in the more advanced part of the class.
 
 
 
* General purpose '''scientific plotting tools'''. At least one of the following SW should be available: [https://plasma-gate.weizmann.ac.il/Grace/ (XM)Grace], [http://www.gnuplot.info Gnuplot], or python with [https://matplotlib.org matplotlib] support.
 
 
 
 
 
Several options are available:
 
* Opt1: Using the '''Quantum Mobile''' virtual machine (VM);
 
* Opt2: Connecting to '''existing machines''', compliant with the class, as provided by the tutors
 
* Opt3: Installing '''your own machine'''
 
=== Opt1: Using Quantum Mobile ===
 
 
 
Quantum mobile is a ready-to-go VM, thought to provide all MaX flagship codes (incl QE) together with AiiDA seamlessly integrated in a plug-and-play linux (Ubuntu) environment. Quantum Mobile is [https://www.materialscloud.org/work/quantum-mobile available] on the [https://www.materialscloud.org MaterialsCloud] portal.
 
 
 
Step by step installation:
 
* Download the latest version of Quantum Mobile, following the link here: [https://github.com/marvel-nccr/quantum-mobile/wiki https://github.com/marvel-nccr/quantum-mobile/wiki]. By doing this you'll obtain a VM image.
 
* If not available, install [https://www.virtualbox.org VirtualBox] to run the Quantum Mobile VM.
 
* Double click on the Quantum Mobile to start the VM.
 
* At this point, you should see a virtualised Ubuntu OS. By opening a terminal you'll see that pw.x (and the other required executables) are available. Among others, all executables from the QE distribution, XcrySDen, Grace, gnuplot, and python are all pre-installed.
 
* The unix accounting within the VM is as follows: 
 
    user: max    passwd: moritz
 
* Further information about Quantum Mobile installation can be found here: [https://github.com/marvel-nccr/quantum-mobile/releases/ https://github.com/marvel-nccr/quantum-mobile/releases/].
 
 
 
=== Opt2: Connecting to existing machines ===
 
 
 
=== Opt3: Installing the needed software in your own machine ===
 
 
 
If you want to use your desktop or laptop, be sure you have the following software installed:
 
 
 
* [http://www.quantum-espresso.org Quantum ESPRESSO] package
 
* Structure visualization software ([http://www.xcrysden.org XcrySDen] or [https://jp-minerals.org/vesta/en/ VESTA])
 
* A molecular editor (e.g. [https://avogadro.cc Avogadro])
 
* General purpose '''scientific plotting tools'''. At least one of the following SW should be available: [https://plasma-gate.weizmann.ac.il/Grace/ (XM)Grace], [http://www.gnuplot.info Gnuplot], or python with [https://matplotlib.org matplotlib] support.
 
 
 
 
 
=== Training material ===
 
In order to download the training material needed for this class, clone the [https://github.com/max-centre/LabCQM LabQSM] repository from [https://github.com/ GitHub], by issuing the command:
 
  >  git clone https://github.com/max-centre/LabCQM.git
 
 
 
No passed request is be prompted, and a folder called LabQSM is created locally. Inspect the contact of the folder by typing:
 
  >  ls LabQSM/
 
  >    LAB_1    LICENSE  README.md docs      tools
 
 
 
On every new lecture, or when mentioned by the tutors, update the repository by typing:
 
  >  cd LabQSM
 
  >  git pull
 
 
 
You are now all set and ready to start the hands-on part.
