no candidatesList.txt file

[guten-tag]

Hi,
When I finished the command:
python controller.py 1
It actually generate candidate pairs. However there is no candidatesList.txt. So when I continue run:
./runPredictor.sh
The out_9900 file "found 0 candidate files". And of course, the clonepairs_type2_9900.txt is empty.

So I wonder if there is something that I miss when running the code.
