There is something wrong in step2 when detect file clone

[XueiuR]

When I run this sourererCC for detecting a whole project, it works will. But when I detected only one file, it blocked.
I accessed the openssl in github and use two visions of it to test SourcererCC. When the tested project is whole, SourcererCC worked and I can got the result. But when I only detect the same files in two visions during step2, it cannot have a result, as the picture show.

emmmm, if the SourcererCCcan can only detect a whole project? Or is there anything wrong when I run this program? I run the SourcererCC as the pipeline1.txt in the virtual machine.
