ESB Webinar Series – No. 17 – Python II – Automated execution of python scripts for medical image processing and bone FEA
Computational work in the field of bone biomechanics follows specific workflows – such as image processing, meshing, model creation, FEA solution and post-processing. In each step, a lot of data is read in and output. With large amounts of data, this can become very demanding, time-consuming, and error-prone. Moreover, such analyses should be repeatable and verifiable. So-called workflow and provenance management systems can be very helpful here. These combine customized software scripts with input and output data of any size, avoid manual intervention, and provide an overview of the individual processing steps. In this webinar, the Medtool software tool will be presented (www.medtool.at).
During this webinar, attendees will learn about:
- Understand the idea behind provenance management systems.
- Automate such analysis workflows.
- Get an idea of the possibilities to make your scientific work more effective with it.
We recommend to people attending the webinar to:
- Take a look at the website www.medtool.at, watch the “Getting Started” webinar and read the introduction in the user manual (see documentation page).
- If you like to use Medtool during and after the webinar (free trial till end of 2023), write an email to: firstname.lastname@example.org
