In each buggy file under the path /Defects4J, there is a file named like "Chart_1_info".

Here I know the "t" represents the test case which the buggy program fails. But what does "s" in the third line mead? Without this knowledge, we could not reproduce other experiments in this dataset.
Also, I wish the authors will release the source code of CapGen since this paper has already been published. Open access will help us better understand the working-flow of this tool.
