2011-10-05 15:59:11 -0500	answered a question	Save many ROIs with same time stamp inside a bag file How about creating a new message type to hold the ROIs and masks, e.g. `sensor_msgs/RegionOfInterest[] rois sensor_msgs/Image[] masks` stored at the same timestamp of the image?

2011-07-27 06:23:46 -0500	answered a question	Slam gmapping tutorial troubleshooting Khiya, I'd like to reproduce your problem. Can you please give me a link to `aptLaserData.bag`? Also, I reindexed the `basic_localization_stage.bag` referenced in the tutorial. If you have a chance, can you try downloading the bag again and see if you have the same problem.

2011-03-17 17:32:14 -0500	answered a question	Analyzing ROS messages `rxbag --record /topic` will allow you to see what's stored in messages published on a topic. You can view the contents textually, plot numerical values, or view image messages.
2011-03-16 10:20:54 -0500	commented answer	rosbag meta data A ticket would be good; a patch better. We've held off on implementing this as there's room for abusing the feature, but it's been demanded enough and is useful in enough circumstances that I think we should pull the trigger. I like your -m option.

2011-03-15 19:11:03 -0500	answered a question	rosbag meta data No, there isn't currently functionality to do that. There's room to extend the format in future versions of ROS to add small amounts of metadata, however, as the file header record is padded out to 4KB.
2011-03-15 19:06:26 -0500	answered a question	Renaming a topic inside a bag file I'd use the `rosbag` Python API: `from rosbag import Bag with Bag('Y.bag', 'w') as Y: for topic, msg, t in Bag('X.bag'): Y.write('/b_topic' if topic == '/a_topic' else topic, msg, t)`
