A tutorial for fitting the DDM to conflic task

I was wondering if there's a sample data structure or a basic tutorial that can fit HSSM to conflict tasks and study CSE (congruent/incongruent, and previous congruent/previous incongruent)? Thank you!

The issue does not name a file, test, or existing tutorial. Start by reviewing HSSM's current documentation and examples to find where tutorials and sample data are organized, then determine how a conflict-task dataset and CSE analysis should be presented. Done means a newcomer can follow the tutorial to fit the requested task.
