GROMACS modification: No
When I run eneconv
program with -dt parameter equal to same dt of 4.0 ps used for trajectory out in simulation I don’t get any warnings as in:
gmx eneconv -f Solv${state}.edr -o last_half.edr -b 5000 -e 10000 -dt 4
but if I want save every other energy frame run such as this:
gmx eneconv -f Solv${state}.edr -o last_half.edr -b 5000 -e 10000 -dt 8
I get these WARNINGS but I can still run gmx energy
, however I don’t know if I can trust it.
