merge rosbag

[HJMGARMIN]

Thank you for your great work.
I downloaded the dataset and I found that there are ten rosbags in each package. I want to know how to merge them into one rosbag.

Hi,

You can either play them with rosbag play *.bag --clock --other-options this will play all the bags in the folder in the correct order.

If you want to merge them you can use this or write your own script to read the bags and write the data you need in a new one using the official APIs.

Thanks for your reply. It's useful.

No problem!

Also, note that the bags may be compressed (forgot to mention that in the readme).

you can decompress them before playing with
rosbag decompress *.bag This will automatically decompress all the bags in the folder.

If I do not decompress the bags, is there any influence when I rosbag play them.

That depends on your system. Probably, yes.
