 datasets provide by te first step. This step is usually done many times and is then naturally optimized by the reduced datasets to be read. 
 
 To perform this 2-steps approach  **pp-ana** contains two main post-processing components: 
-- (`opmdfilter.py`) the filtering program that processes in parallel OpenPMD data files and generates [Parquet files](https://parquet.apache.org/) 
+- (`opmd_filter.py`) the filtering program that processes in parallel OpenPMD data files and generates [Parquet files](https://parquet.apache.org/) 
 for both field and particle data
-- (`analyze.py`) the main analysis program that reads the generated [Parquet files](https://parquet.apache.org/)  
+- (`opmd_pq_reader.py`) the main analysis program that reads the generated [Parquet files](https://parquet.apache.org/)  
 to produce histograms and visualizations ([matplotlib](https://matplotlib.org/)).
