This folder contains MATLAB code to process ROS bag files, the official message storage format for ROS.
In order to use the software, you need to have the Robotics System Toolbox installed. You can check installed toolboxes by running ver at the command line
You also need the ROS Custom Messages toolbox in order for MATLAB to recognize custom ROS messages
Before running, ensure that you have the folder named packages in the same directory as the readBag.m file. The rosgenmsg command generates MATLAB interfaces to custom ROS messages/services based on the message / service definitions inside packages.
Before running readBag.m, uncomment the rosgenmsg and run just this command (Highlight the entire command and press F9). Follow the instructions printed to the MATLAB console. You may need to create the javaclasspath.txt file if no such file exists. This command generates new folders and files with the packages folder, in packages\matlab_gen\msggen
To save this messages types for future MATLAB sessions, uncomment the addpath / savepath command, replace path_to_msggen with current_directory_path\packages\matlab_gen\msggen, where current_directory_path is the path to the readBag.m file on your machine.
At this point, you can comment out the rosgenmsg and addpath/savepath commands, and run the entire file.
- If you add, delete, or modify any of the message types (defined inside
packages/barc/msg/), delete the matlabgen folder and rerun therosgenmsgcommand.
