Hi Everyone,
I'm trying read a rosbag it into MATLAB, create a new topic based on the messages in the bag then write all of the messages out (including those from the old bag file) to a new bag file. I am able to accomplish reading of the bag file using the following [MATLAB toolkit](http://www.mathworks.com/hardware-support/robot-operating-system.html?requestedDomain=www.mathworks.com). But this toolkit does not appear to support writing rosbags.
My questions are as follows.
1. Is anyone aware of a MATLAB tool that would allow me to write message to a rosbag in MATLAB?
2. I'm considering trying to write my own robag writer in MATLAB is there any reason that this would be a bad idea?
My apologies for repeating [this](http://answers.ros.org/question/222225/how-to-write-to-a-ros-bag-in-matlab/) question but there weren't any answers with useful information.
Thanks,
~ John
