I’m trying to create a surface slab using VESTA, but I’ve been stuck on how to properly use the transformation matrix for the past three months. Most YouTube tutorials demonstrate how to visualize or slice structures, but they don’t clearly explain how to find or apply the correct transformation matrix to create a specific slab orientation.

If anyone knows an easy and systematic way to create slabs in VESTA, especially including how to determine the transformation matrix, I would really appreciate your guidance. Also, if there are any clear tutorials or resources (videos, articles, etc.), please do share the links.

Thanks in advance!
