 Before you submit your pull-request, please verify and check all below items
 
 - [ ] You have only modified the minimum number of lines that are necessary for the update; you should never add/remove white spaces to other lines that are irrelevant to the desired change.
-- [ ] You have run `make pretty` (requires `astyle` in the command line) under the `src/` folder and formatted your C/C++/CUDA source codes **before every commit**; similarly, you should run `python3 -m black *.py` (`pip install black` first) to reformat all modified Python codes, or run `mh_style --fix .` (`pip install miss-hit` first) at the top-folder to format all MATALB scripts.
-- [ ] Add sufficient in-code comments following the [`doxygen` C format](https://fnch.users.sourceforge.net/doxygen_c.html)https://fnch.users.sourceforge.net/doxygen_c.html
-- [ ] In addition to source code changes, you should also update the documentation ([README.md](https://github.com/fangq/mcx/blob/master/README.md), [mcx_utils.c](https://github.com/fangq/mcx/blob/v2023/src/mcx_utils.c#L5029-L5236)https://github.com/fangq/mcx/blob/v2023/src/mcx_utils.c#L5029-L5236 and/or [mcxlab.m](https://github.com/fangq/mcx/blob/v2023/mcxlab/mcxlab.m)https://github.com/fangq/mcx/blob/v2023/mcxlab/mcxlab.m) if any command line flag was added or changed.
