GROMACS version:    2021.2-MODIFIED
This program has been built from source code that has been altered and does not match the code released as part of the official GROMACS version 2021.2-MODIFIED. If you did not intend to use an altered GROMACS version, make sure to download an intact source distribution and compile that before proceeding.
If you have modified the source code, you are strongly encouraged to set your custom version suffix (using -DGMX_VERSION_STRING_OF_FORK) which will can help later with scientific reproducibility but also when reporting bugs.
