GROMACS version: 2020.1
GROMACS modification: No
The gmx grompp starts fine and then fails to produce the *.tpr file by giving the below error:
Number of degrees of freedom in T-Coupling group Other is 182768.00
Number of degrees of freedom in T-Coupling group SOL is 556035.00

I thought it might be a problem with the gmx grompp by itself in 2020.1 version as the gmx mdrun works fully fine in the same machine using the *.tpr file (for the same MD system) generated somewhere else.
Additionally, the gmx grompp of older versions of Gromacs works also fine in the same machine.
