Dear,

I want to run production, but I want to make several replicas independently, I am using an NPT assembly for production and I am turning off the continuation command, and adding the following code,

; Velocity generation  
gen\_vel = yes; assign velocities from Maxwell distribution  
gen\_temp = 300; temperature for Maxwell distribution  
gen\_seed = -1; generate a random seed

it would be correct?

best,

Geo.
