Script for reading a Canberra Nuclear File (CNF) form GENIE2000 software.
It can be used as a stand alone script or as a module.
Optionally, it generates a text file with the relevant information read from the CNF file. The output file name is the input file plus '.txt' extension.
When used as a module, it returns a dictionary with all the magnitudes read. Depending on the data available, its keys may be:
Sample id
Channels
Sample unit
Sample name
Channels data
Energy unit
Energy coefficients
Shape coefficients
Left marker
Total counts
Number of channels
Start time
Counts in markers
Right marker
Sample type
Sample description
User name
Live time
Energy
Real time
Measurement mode
MCA type
Data source
read_cnf.py: CNFreader python scrip.README.md: This filecnf_file_format.txt: CNF binary file description. Taken from cnfconv../Examples/: Folder with examples filesexample_mcs.CNF: Data file aquired with a multichannel analyzer in MCS mode.example_pha.CNF: Data file aquiered with a multichannel analyzer in PHA mode.cs137.CNF: Exxample file of a $^{137}$Cs gamma spectrum (PHA mode).
As a standalone script:
>>> python read_cnf.py name_of_the_file.CNF
('name_of_the_file.CNF.txt' is automatically created)
As a module:
>>> from read_cnf import read_cnf_file
>>> read_dic = read_cnf_file('name_of_the_file.CNF')
>>> read_dic['Live time']
This script was made as a copy of the c program 'cnfconv' written for the same porpouse. That software can be found here:
All the information of the binary file encoding was taken from the file 'cnf_file_format.txt' of the above repository.
- Markers information is not being read correctly.
- If the CNF file are obtained in a MCA mode, the live and real time are not read correctly.
- Additional data must be read in case of a file from MCA mode (mainly dwell time).
