If there is an error or mistake in one of my GROMACS tutorials, or if something is unclear, please open an issue, and I will be happy to address it. If you have a general question about GROMACS see the GROMACS documentation. You can also direct general questions about GROMACS to their mailing list. Since I know that the GROMACS community is very helpful, general questions about GROMACS that are directed toward me will probably be left unread.
If you have questions about any software that I have published on Github, please file an issue on the specific project’s Github page.
If you have an opportunity that you think I will find interesting, send me an email.
