I generate a new cpin and prmtop file using the following command.
/home/srabani/Downloads/amber24/bin/cpinutil.py -p amber18.prmtop -o
amber24.cpin -resnames HIP AS4 GL4 TYR LYS -op amber24.prmtop
Now the run is running well. But It starts from 0 ns. But I already have
100 ns run. Is there any possibility to restart the run?
