Writing and editing a tf_static message to an already recorded rosbag

edit

Hello,

I have a rosbag that was recorded when there were missing and incorrect \tf and \tf_static messages being broadcasted. I want to be able to edit the \tf and \tf_static messages so that I can write the correct transformations between the frames.

As of now, I am unable to use the rosbag package with Python to playback the rosbag and edit it's information. I specifically am unable to write a message to \tf_static. Is there any way to achieve this method of editing \tf_static messages or writing new ones on top of an existing bag?

Thank you!
