Unable to use allan_variance

[Hateley123]

I am following the instructions on how to use your system and I was able to output the information into a new bag using step 2. However, when I true to do step 3 I get the following error if I have roscore running

Error
ig-handle@ig-handle:~/catkin_ws/src/allan_variance_ros$ rosrun allan_variance_ros allan_variance /home/ig-handle/catkin_ws/src/ig_handle/scripts/cooked_rosbag.bag

If i do not have roscore running then I get the following error

Error

[ERROR] [1674847344.161721965]: [registerPublisher] Failed to contact master at [localhost:11311]. Retrying...

Now in both instances I know the file exists because i see in the directory and when I press tab it selects the file in the terminal. Do you know how to fix this problem
