Hi friend. I have a problem. I want to run my bag file with Karto. So I use static transform publisher to connect frames.
My frames.pdf is here: 
I set the fixed frame to the odom, My LaserScan sometimes red, sometimes green:
Like this(Red): 
But it changes.
When I set fixed_frame to the base_link, LaserScan seems good, but at this time, map going to red(Error)sometimes and green sometimes. And it says me "No transform from [map] to [base_link]"
This is an error or normal? Is my TF tree correct?
