lst2ascii

lst2ascii is a little piece of software that converts to ASCII the list-mode files generated by MPA3 from FAST ComTec. It is written in pure C and it needs just some standard libraries. It was successfully compiled and executed with

• clang and gcc in OS X;
• clang and gcc in Linux;
• MinGW in Windows.

Usage

The program needs to be run from the command line with at least one argument:

lst2ascii <file_name.lst> [output_file]

The first option is the name of the list-mode file that will be converted, the second option is optional and specifies the output file. If no [output_file] is given, a .lst file extension is assumed and changed to .txt, thus output will be: file_name.txt [output_file] should have no extension, .txt will be added.

Once run, the program gives some information about the acquisition:

Written events: 5591
Run time: 78.632 s
Average rate: 71.1034 Hz

ADC 0:
Run time: 78.57 s
Events: 4326
Average rate: 55.0592 Hz
Dead time: 0.0788498%
Range: 8192

ADC 1:
Run time: 62.412 s
Events: 4326
Average rate: 69.3136 Hz
Dead time: 20.6277%
Range: 8192

ADC 2:
Run time: 78.416 s
Events: 5484
Average rate: 69.9347 Hz
Dead time: 0.274696%
Range: 8192

ADC 3:
Run time: 78.371 s
Events: 5483
Average rate: 69.9621 Hz
Dead time: 0.331924%
Range: 8192

Output format

The output is a text file with four columns:

1. event number;
2. time elapsed from the beginning of the measurement, in milliseconds;
3. the active ADC number;
4. the datum acquired by that particular ADC in that event. If there are some ADCs acquiring in coincidence, the results will have the same event number.

Event	Time [ms]	ADC	datum
1	1	0	8191
1	1	1	66
1	1	2	1663
1	1	3	1533
2	14	2	320
2	14	3	8001
3	58	0	5432
