tactime - tpcclib 0.8.0 © 2023 by Turku PET Centre

Increase or decrease the sample (frame) times in regional or blood/plasma
TAC files.
Samples with negative times are not saved by default.
Time must be given in the same units that are used in the datafile.
 
Usage: tactime [Options] tacfile [-]time [outputfile]
 
Time can be given as positive or negative value directly in the command
line, or in an ASCII file which contains a line with the time change value
in the following format: 'time_difference := time'.
Alternatively, time specified in that file with 'Ta' or 'start_time' is
subtracted from sample times.
If 'peak' is given as time, TAC(s) are moved to start at the peak time
or at start of peak frame.
If 'gap' is given as time, TAC(s) are moved to remove initial gap time.
 
Options:
 -decay
     Physical decay correction is changed with change in sample times;
     without this option, radioactivity values are not changed.
     Note that this option will provide correct result only if time unit
     setting in datafile is correct.
 -i=<isotope>
     Isotope must be known for the decay correction.
     Accepted isotope codes are for example F-18, C-11, and O-15.
     Isotope code can also be specified in input file in format
     '# isotope := C-11'.
 -keepnegat
     Samples with negative sample times are not removed from output.
 -keeptimes
     While correction for physical decay is changed with option -decay,
     sample times will not be changed.
 -nogap
     Possible gap between time zero and first sample is filled.
 -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.
