GROMACS version: 2020.2 & 2020.3
GROMACS modification: No
Here post your question:
I simulated one metal ion in a cubic water box, but after minimization, the numbering of the metal ion, all the water and counterions were changed to 1, while they were in ordered numbering in the initial gro file. I tried it with both 2020.2 and 2020.3. I have never had this problem before. Is this a new feature, or a bug? Thanks a lot!
All the best,
