unable to open file 'config1.cfg' (benchmarks)

edit

Hello,

I have been following the tutorial on benchmarking according to this link. I was able to make a configuration file (I names it config1.cfg like in the tutorial) after I added some scenes and queries to my database.

[scene]
name=No_obstacles_1
runs=2
timeout = 10
output = mylocation.log


[plugin]
name=ompl_interface/OMPLPlanner
planners=RRTConnectkConfigDefault PRMkConfigDefault
runs = 10

When I try to run the benchmark I use the following command:

roslaunch epson_moveit_generated run_benchmark_ompl.launch cfg:=config1.cfg

But it fails at a certain point:

So it's unable to open or even find the config file. Can someone explain me why this error occurs and how I can solve it?

I am running ROS hydro in ubuntu 12.04
