Oscillation Data Analyzer

This project provides a C++ program that reads oscillation data, processes it, and generates histograms using the ROOT framework. It deals with data from two sources: prompt data and null prediction data. The program parses these files, processes them to map segment data to baseline values, and creates ROOT files and histograms for analysis.

Features

• Parses oscillation data from text files with configurable columns.
• Maps segment data to baseline values using a segment map file.
• Creates ROOT files with oscillation data.
• Plots histograms of oscillation data using the ROOT framework.

Dependencies

To run this project, you need the following installed on your system:

• ROOT - A framework for data processing and visualization.
• A C++ compiler, such as g++.

Code Structure

• DataPoint class: Represents a data point with fields like bin center, IBD counts, total stats error, background counts, and background stats error.
• SegmentMap struct: Holds the mapping between segment and baseline values.
• OscillationAnalyzer class: Handles file parsing, ROOT file creation, and histogram plotting.

Files:

• 1.1_Osc_SegmentMap.txt: Contains mapping from segment to baseline.
• 1.4_Osc_Prompt[segment].txt: Contains prompt data for different segments.
• 1.6_Osc_NullOscPred[baseline].txt: Contains null oscillation predictions for different baselines.

How to Use

1. Clone the repository:

   git clone https://github.com/RalAngelo/OscillationDataAnalyzer
   cd OscillationDataAnalyzer

2. Make sure you have ROOT installed. You can check by running:

   root --version

3. Compile the code:

   g++ -o oscAnalyzer oscAnalyzer.cpp `root-config --cflags --glibs`

4. Prepare the data files. Make sure you have the necessary datasets:

   • 1.1_Osc_SegmentMap.txt
   • 1.4_Osc_Prompt[segment].txt
   • 1.6_Osc_NullOscPred[baseline].txt

5. Run the executable:

   ./oscAnalyzer

6. The program will process the files, generate ROOT files (oscPrompt.root and oscNull.root), and produce histograms saved as PNG images:

   • Fig40_Reconstructed.png
   • Fig40_1_Reconstructed.png

Code Explanation

The code consists of the following steps:

1. File Parsing: Data is parsed from text files into DataPoint objects.
2. Mapping: Segment data is mapped to baseline values using a segment map.
3. ROOT File Creation: The parsed data is stored in ROOT files for further analysis.
4. Plotting: Histograms of the data are plotted and saved as images.

Customization

• Modify the segment and baseline range by adjusting the loops in the processFiles method.
• Change the appearance of the histograms by modifying the plotHistograms and plotHistograms2 methods.
• If your data format changes, adjust the parseFile method to handle different column structures.
