abssfch - tpcclib 0.7.8 © 2022 by Turku PET Centre

Scanditronics and GEMS on-line blood sampler have sometimes failed to
correctly record the count data from either of the two channels, seen as
substantially lower or zero counts.
Use this program to calculate the channel1-to-channel2 ratio of coincidence
counts, or, to correct the data from failed channel using user-provided
correct channel1-to-channel2 ratio.
 
Usage: abssfch [options] abssfile [ratio]
 
Options:
 -o=<filename>
     Name for corrected file; by default the original file is overwritten.
 -fix=<channel>
     Set the channel (1 or 2) to fix; by default the channel with lower
     counts is fixed.
 -h, --help
     Display usage information on standard output and exit.
 -v, --version
     Display version and compile information on standard output and exit.
 -d[n], --debug[=n], --verbose[=n]
     Set the level (n) of debugging messages and listings.
 -q, --quiet
     Suppress displaying normal results on standard output.
 -s, --silent
     Suppress displaying anything except errors.
 
Example 1: calculate channel1-to-channel2 ratio.
     abssfch us1328.bld
Example 2: correct the failed data with given channel1-to-channel2 ratio.
     abssfch -o=us1328_corr.bld us1328.bld 0.982
