absstime - tpcclib 0.8.0 © 2023 by Turku PET Centre

Correct the sample times in Allogg, Scanditronics, or GEMS ABSS on-line
blood sampler data file by giving the correct sampling start time in format
hh:mm:ss. If the new sampling start time is not given, program lists
information on the current sample times on the screen.
Use this, if sampling was accidentally started later than the PET scan.
In old Allogg files the sampler start time is given before the sampler
data lines in format hhmmss. In new Allogg files individual sample time is
stored for each sampling frame.
In Scanditronics data files the correct sampling start time is in the file
headers; however, in old Scanditronics data files the headers do not contain
time, but it is read from the first sample data line.
In GEMS data files the time in file headers is not the sampling start time,
but time is read from the first sample data line.
If new sampling time is given and it is different than the current sampling
start time, then all sample times in the sampler data file are changed.
Decay correction is not changed.
Notice that the original data file is overwritten by default.
Usage: absstime [options] abssfile starttime
     Name for corrected file; by default the original file is overwritten.
 -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: List the start times from ABSS data and ECAT image, and
set the ABSS start time based on the PET scanner start time.
