Accleration not matching

Dear team,
I tried to compare the acceleration that I get from the acceleration recorder command with the STKO Postprocessor. There is a difference between the two. I have attached the image below. Also If I compare the acceleration at the top story, there is a huge difference. Any suggestions in this regard will be appreciated.
Regards,
Zeeshan Bhat

Sorry for the late response.
Actually, the results are correct:
You are using the uniform excitation, which means the output accelerations are relative.
In STKO you are recording the relative acceleration,
while in the node recorder you added the timeSeries (option -timeSeries 2) which makes the output absolute.
Try to remove the -timeSeries 2 option and you will see the same output
