Problem with files being written and read by different versions of GROMACS

Hi,
maybe this post helps

Reading tpx file version 119 with version 103 program

GROMACS version: 2020.2 I am following the “KALP-15 in DPPC” tutorial on my computer with GROMACS 2020.2, and I try to run the NPT equilibration in parallel on a cluster of my department, whose GROMACS is version 5.1.2. I submit my job and the output file reads: Fatal error: reading tpx file (npt.tpr) version 119 with version 103 program Is this because the tpr file produced by a latter version of GMX cannot be read by an older GMX? If so, how to deal with the problem?
