Try changing your pcd file to binary format, it might be ASCII.

@AM97 What do you mean physically? Do you mean how the data from the two sensors are related to each other? If yes, ther

I am working on a Ubuntu 14.04 system with ROS Indigo. I currently have a python script in the /home/usr path that is launched by a desktop file using auto-start. I use roslaunch inside the python script to bring up other ROS nodes/packages elsewhere in the system using import roslaunch and rospy. I have sourced the ROS package (/opt/ros/indigo/setup.bash) in bashrc as well as the other packages I am running through the script. The problem is that when I reboot the system, my python script executes but comes up with the error message "no module named rospy" (or roslaunch). I tried starting a roscore using the subprocess.Popen('roscore') in the python script as well but the error was "No such file". I want to run some operations in the python program before the "roslaunch" operation and all this needs to execute at system boot each time. Any help is appreciated, thanks in advance!

Hello,

I am trying to run two different packages together for accumulating data from two different systems/sensors - Eg: roslaunch a_b ab.launch, roslaunch x_y xy.launch. I am currently calling two python programs to record the data but I want to be able to launch it simultaneously from the same python script so that I can manipulate the data from the two sensors inside one script. Is there a clean way of doing this? Thanks in advance!
