Hello Experts,
I am an IT professional who is trying to simulate a healthcare environment on a large scale and hence we are using software to simulate that workload on our systems, So I am basically trying to get 3D slicer to open up a nrrd file \>\> Go to “Volume Rendering” \>\> Click on Volume \>\> Select a Preset \>\> Change rendering to GPU \>\> look at the 3D image for 30-45 seconds and close the application.
I was able to automate the workflow using some scripts and automated mouse movements, the result is pretty decent ( You can watch the script in action @ [https://youtu.be/-DWZDO4e8ns](https://youtu.be/-DWZDO4e8ns) ) but I was curious to know if I can simulate these steps using only Python or only keystrokes.
Regards,
A new guy in 3D Slicer world

There are several self-tests that perform complex workflows, including loading data, setting up various visualizations, and simulating keystrokes and mouse movement.
