I am new to 3D Slicer. I am looking for recommendations on training courses to get me up to speed. Thank you for your help.
The PerkLab bootcamp materials are great: GitHub - PerkLab/PerkLabBootcamp: Materials for the yearly PerkLab bootcamp course
The upcoming Slicer Project Week is also a good opportunity to learn about Slicer. Especially if you have a specific task you want to solve then you can write it up as a project and you can get help from experts to get started or if you get stuck.
