Hi, I'm trying to do this part 'Making new bagfile from kitti dataset'

Question

enter image description here

Hi, Im trying to do LeGO-LOAM with https://github.com/Mitchell-Lee-93/kitti-lego-loam

Download odometry dataset(color or gray, velodyne, calibration, ground truth) from : http://www.cvlibs.net/datasets/kitti/eval_odometry.php and Merge them all in one dataset directory

Edit the launch file gedit ~/catkin_ws/src/kittibag/launch/kittibag.launch Change 'dataset_folder' and 'output_bag_file' to your own directories

Run the launch file: roslaunch kittibag kittibag.launch

After compiling, I downloaded the whole kitti data files. But I dont know how to merge them all in one dataset directory. As you can see in the picture, I made a data set folder and ran bagfile, but it didn't work well. Do you know how to solve this?
