Hi all,
I am using Amber18 to run NEB simulations on my protein + water system. I minimized both the end states and made sure the prmtop file generated is the same for both the end states. Then, I am following Tutorial A5 on NEB calcs on Alanine dipeptide.
The issue is when I run step 4 to generate images and heat the system, my end states are also undergoing a change in their conformation, which should not happen (attached explicit.1heat.sh).
When I try doing the calculations on Alanine dipeptide in implicit solvent (as done in the tutorial), it works fine. So, I thought maybe it has something to do with my explicit solvent. But when I do the calculations on my system using implicit solvent, the conformations of my end states are still changing (attached implicit.1heat.sh).
I am not able to figure out why this is happening. I would really appreciate if someone could help me out with this. I have attached my input scripts for both implicit and explicit solvent cases here.
Thanks,
Madhur Aggarwal
