[Marcello-Sega]

Please make sure that your pull request satisfies the following requirements:

If you have fixed a bug

• [ ] Explain the fix in the pull request, and add a minimal code that reproduces the bug & the fix
• [ ] Add the minimal code to the docstring tests if possible

If you have written a new method in one of the available modules

• [ ] Document it with a docstring
• [ ] Add a short, deterministic test in the docstring
• [ ] Explain briefly what the patch is about in the pull request

"Big" Pull requests

• [ ] Submit one commit per issue/change if possible.
• [ ] There can be many commits in a pull request, but please try to group them thematically (e.g., avoid git commit -a)
• [ ] In case you have many small commits, you can always rebase them in your tree before submitting the pull request.
• [ ] Pull requests that include merge commits won't be in general accepted
• [ ] If you make a pull request from your master branch, you do it at your own risk (see also the point above)

If you have implemented a new module

• [ ] All main methods should be documented
• [ ] Tests should be added to the docstrings
• [ ] The module works with as many different input file formats as possible
• [ ] Interfacial atoms (if calculated) are marked as such, similarly to the other modules
• [ ] The module does not change the configuration (positions, velocities,...) as loaded by MDAnalysis
• [ ] __init__() calls pytim.PatchTrajectory
• [ ] you have prepared a section to be added to the online manual
• [ ] you have prepared one or more sample jupyter notebooks
• [ ] you have added one or more minimal example python scripts to be added to pytim/examples/
