Hello everyone,

I couldn’t figure this out in in.msd.2d where a line reads :

variable twopoint equal c_msd[4]/4/(step*dt+1.0e-6)

I know Einstein’s equation : msd=2*n*D*dt where n is the number of dimensions. What does this 1.0e-6 represent? Shouldn’t this be simply :
variable twopoint equal c_msd[4]/4/(step*dt)

Thanks,

Sonu Kumar
