abssbkg - tpcclib 0.8.0 © 2023 by Turku PET Centre
Subtract constant background radioactivity in on-line blood sampler data.
The average of coincidence cps from 0 to specified time is calculated
and subtracted from the data; in case of Scanditronics/GEMS this is
a separate process for the two detector pairs, and in case of Allogg
separate for the two channels.
The background radioactivity is assumed to be stable during the assay
(not decaying); do not use this program in case of momentary background
radiation.
Notice that the original data file is overwritten by default.
Usage: abssbkg [options] abssfile time
Options:
-o=<filename>
Name for corrected file; by default the original file is overwritten.
--dry
Dry run: background is shown but data is not changed.
-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 background from 0-60 s and subtract it.
abssbkg -o=us1328_corr.bld us1328.bld 60
Example 2: calculate mean radioactivity [cps] from the measurement.
abssbkg --dry us1328.bld 999999
