Output of additional files (detectors, induction loops) are not being generated

Question

Output of additional files (detectors, induction loops) are not being generated. I used a simple scenario, just to see how things work. But I cannot see or maybe these files are not being generated. I added them at launch.xml and sumo.cfg as additional files. This is the code for detector.xml :

<additional>
    <laneAreaDetector id="E2" lane="1to2_0" pos="15" endPos="20" length="20.0" friendlyPos="false" freq="5.890e9" file="ostie.xml" timeThreshold="1" speedThreshold="3.6" jamThreshold="10.0" />
</additional>
<additional>
    <inductionLoop id="myLoop1" lane="1to2_0" pos="16.0" freq="900" file="out.xml" />
    <inductionLoop id="myLoop2" lane="1to2_0" pos="100.0" freq="900" file="out.xml" />
</additional>

The file out is empty. Please help!

Thanks in advance.

You might be using sumo-launchd.py of Veins to run your simulation. If so, the SUMO simulation will execute in a temporary directory (that is, by default, deleted after the simulation concludes). You will either turn this off (see the output of --help) or create the output files in another directory to retain them.
