Hi, I am trying to analyze the Lipid-Solvent bond network with hbond using this script:

But I ran into this issue:

1/3616/var/spool/slurmd/job54592996/slurm\_script: line 15: 11920 Done echo -e “2\n4”  
11921 Segmentation fault | gmx hbond -f md.xtc -s md.tpr -n …/index.ndx -hbn hbond.ndx

Is this an issue specific to gromacs or is it something with the job I ran? What are some suggested fixes?
