How can I calculate displacement from acceleration but correcting for the offset?

Basically from the acceleration cruve I can get the curve of velocity and displacement doing something like this:

NewVel = cumtrapz(time, acceleration);

NewPos = cumtrapz(time,NewVel);

However I will get a ramp (an offset) how can I remove it to get proper displacement?
