tactime - tpcclib 0.7.4 © 2019 by Turku PET Centre
Increase or decrease the sample (frame) times in regional or blood/plasma
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.
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.
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'.
Samples with negative sample times are not removed from output.
While correction for physical decay is changed with option -decay,
sample times will not be changed.
Possible gap between time zero and first sample is filled.
Display usage information on standard output and exit.
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.
Suppress displaying normal results on standard output.
Suppress displaying anything except errors.
