tactime - tpcclib 0.7.4 © 2019 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.
 
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.
