Tutorials

Python

If you are not familiar with Python please read What is Python?.

If your ASE scripts make extensive use of matrices you may want to familiarize yourself with Numeric arrays in Python.

ASE

Most of the tutorials will use the EMT potential, but any other Calculator could be plugged in instead.
