bag file to pcd with intensity

edit

i tried converting a bagfile to pcd and i lose intensity. I used the following command:

rosrun pcl_ros bag_to_pcd <input_file.bag> velodyne_points <output_directory>

but the problem that i see that the pcd doesnt include any intensity! Also, my bag doesnt have its own intensity topic and it should be part of velodyne_points!

Thank you guys for the help! Ish

Edit: hi Peter, Yes, i tried my bag file on riviz and i have differrent intensity levels! BTW, this is a sample of what i see when i try to extract XYZ and Intensity:

12.6505 -1.36753 -22.8321 6
-15.0315 -1.33794 -20.7 6

the intensity coordinates (last coordinate) increment in an orderly fashion. I dont believe this is correct!

Thanks,
