SUMMARY

The forum discussion centers on parsing MCNP output files, specifically the MCTAL file, using MATLAB. Users express difficulty in reading the MCTAL file directly due to its ASCII format. A suggestion is made that if one understands the ASCII format, they can utilize MATLAB functions to read these files effectively. A member has reportedly shared a MATLAB code for this purpose, which can be found in the linked thread.

PREREQUISITES
  • Familiarity with MCNP (Monte Carlo N-Particle Transport Code) output files
  • Understanding of MATLAB programming and .m file structure
  • Knowledge of ASCII file formats and data parsing techniques
  • Experience with MATLAB's file input functions, such as fopen and textscan
NEXT STEPS
  • Research how to read ASCII files in MATLAB using fopen and textscan
  • Explore existing MATLAB scripts for parsing MCNP MCTAL files
  • Learn about data visualization techniques in MATLAB for MCNP output analysis
  • Investigate the MCNP output file structure to enhance parsing efficiency
USEFUL FOR

Researchers, nuclear engineers, and MATLAB users involved in MCNP simulations who need to analyze and interpret MCTAL output files effectively.

Hello! I am really glad to find this forum!

I was wondering if anyone has a MATLAB code to parse the MCNP output file MCTAL? I did some Lattice simulation but it seemed hard to read the MCTAL file directly..

Best regards

I'm not familiar with MATLAB, but as far as I can tell, .mctal files are ASCII format, so if one knows the format, one should be able to read the files into MATLAB with whatever function reads an ASCII-format file.

A member here apparently has done that.

How do others read ASCII files with MATLAB?
