Launching the Imaging Notebooks

This tutorial shows you how to launch the Imaging Notebooks for CT reconstruction or for data processing.

1. Connect to the analysis server

Follow this tutorial on how to connect to the analysis.sns.gov machine.

2. Launch the notebooks

Open a terminal by clicking the following icon at the bottom of the window

and type

/SNS/VENUS/shared/software/menu/start_notebooks_with_orion

3. Be patient!

If you are running this command for the first time, it may take up to a few minutes (depending on the traffic on the server) to do the following:

• install the correct application
• prepare the environment

The splash screen will quickly go away, but it will take more time to finish the installation.

Then the ORION window will be displayed

4. Select the notebooks you want to work with

Reduction -> all processing notebooks

Reconstruction -> CT reconstruction

5. Accessing the notebooks

Again, this step may take some time depending on the traffic. At the end you should see a list of notebooks on the left side. If you don’t, click the notebooks folder.

6. Launching a notebook

Click the notebook you want to launch, for example step1_prepare_CCD_images.ipynb for this example.

SHIFT + ENTER on the first cell, if run for the first time, will require you to select the right Kernel.

click the Select Kernel > Python Environments …  and select the default (recommended) kernel listed at the top.

From there, the window should behave like a normal notebook.
