 ### PELIC_compiled.csv
 
-`PELIC_compiled.csv` is a compilation of the files described above. Like `answer.csv`, `PELIC_compiled.csv` is organized such that each row is a unique **text** with a unique identifier, the **anon_id**. Accompanying each text are data relating to the author (from `student_information.csv`) and the course (`course.csv`). These columns have been selected due to their usefulness for conducting linguistic analysis. However, other columns may be added or deleted as desired; see the [build_PELIC_compiled tutorial](#Tutorials) for how to create and manipulate the `PELIC_compiled.csv`.
