[Bug-gmx_MMPBSA]: Different version of Gromacs was incompatible with gmxMMPBSA

Bug summary

Hi, I am trying to calculate the mmpbsa between a protein and peptide. I used gromacs2023.02 and the pbc was removed from the trajectory. But since the version of gmx_MMPBSA is compatible with Gromacs2020, md_2020.tpr was regenerated through the following command: gmx_mpi grompp -f md.mdp -c md.gro -p complex.top -e md.edr -o md_2020.tpr I used the following command to calculate the mmpbsa:
mpirun -np 10 gmx_MMPBSA MPI -O -i mmpbsa1.in -cs md_2020.tpr -ci md.ndx -cg 17 18 -ct md.xtc -cp complex.top However, it gives me the following error MMPBSA_Error: /share/apps/gpu_gromacs/bin/gmx trjconv failed when querying md_C2.xtc
Any help would be appreciated. Thanks!
