Bugs

If you believe you have a bug, please check that you are using the most up to date version of the code.

If that does not fix the problem, please create an issue on GitLab detailing the following:

• The commands you entered
• The error message

Remember to simplify the problem as much as possible in order to provide a minimum working example, e.g. an example for a small molecule rather than one with 100000 atoms.

Then, look at the code, try and figure out what you think is wrong if possible, and include this in your issue.
