Hi,

I have a doubt when I try to build a Map Using Logged Data.

When I create a bag with my robot, I use the next instruction: 
rosbag record -O mylaserdata /base_scan /tf

But, with this instruction is created one .bag file named mylaserdata.bag.active, instead of being created one .bag file with 
the name mylaserdata.bag.

I do not understand the reason for this to happen.

Thanks
