Hi, I just read the message and looked into the files. In my opinion, the issue is the same than above. The file bond-RB-RA.dist.new contains only 0s and therefore dpot.pure_ibi has no valid entries. The setup looks okay to me. I also rerun the gromacs simulation with the tabulated potentials provided in step_001, calculated the RB-RA bond distribution and didn't get all zeros. I'm not exactly sure what happened there.
