====================================
Wannier calculation inside AiiDAlab
====================================

Overview
========
This tutorial will guide you through the process of setting up and running an Wannier calculation for `GaAs`.


Steps
=====


Step 1 Select a structure
--------------------------------
For this tutorial task, please use the `From Examples` tab, and select the `Gallium arsenide` structure.

Click the `Confirm` button to proceed.


Step 2 Configure workflow
--------------------------------

In the **Basic Settings** tab, set the following parameters:

- In the **Structure relaxation** section, select ``Structure as is``.
- In the **Step 2.1: select properties** section, select ``Wannier90``


Then go to the **Step 2.2 Wannier90** tab and select `Compute real-space Wannier functions`.

Click the **Confirm** button to proceed.


Step 3 Choose computational resources
---------------------------------------
We can use the default code.

Then, click the **Submit** button.


Step 4 Check the status and results
-----------------------------------------
The job may take 10~30 minutes to finish.



Here, we compare the Wannier-interpolated bands with the full DFT bands calculation.
