How to understand the result generated by block-level detection

[Kaka727]

Hi
Recently I have figured out the previous problem and get the block-level detection result of the ten projects in my study. But I have lots of troubles understanding it.
For example:

I just don't know what b11 means. How to find the corresponding source code using this result?
And this one

I guess 11 and 12 represent the projects but what does 2 refer to? Since the ten projects are represented by 11 to 20, I can't understand what 2 mean.
These information cannot be accessed in the README file and that's why I come for help.
Thanks~

Hi,
I also got the similar results in block-level clone detection. Have you figured out what exactly 2 and 10429 mean?

Thanks~
