Dear NAMD users,
I have run some protein-lipid coarse grained simulation using NAMD, where I
had used residue based coarse grained method. After running the simulation
for a while, I tried to revert the last coarse-grained structure (without
water and ions) to all-atom structure. I used the CGTools Plugin to revert
the structure which went well. But I am facing problem while annealing the
reverted all-atom structure (after solvated and ionized). I used the
automatically generated annealing configuration file during the reverse
process. The annealing file constrains energy minimization, heating the
system and then cooling it. The problem is- after the minimization steps,
the simulation always crashes saying ' Atoms moving too fast the
simulation has become unstable'. And also I checked the trajectory, the
system i.e atoms does not move at all during the minimization step.
Can you please tell me what am I doing wrong?
Thanks.
