dfttime 2.2.4 © 1999-2012 by Turku PET Centre
For changing sample times in regional or blood/plasma TAC files.
Samples with negative times are not saved.
Time must be given in the same units that are used in the datafile.
Usage: dfttime [Options] <input file> <[-]time value or file> <output file>
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 file with 'Ta' or 'start_time' is
subtracted from sample times.
Options:
-h or --help
Print this message and exit
-d[=<Isotope>]
Physical decay correction is changed with change in sample times;
without this option, radioactivity values are not changed.
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 := Isotope'.
Note that this option will provide correct result only if time unit
setting in datafile is correct.
-keepnegat
Samples with negative sample times are not removed from output.
-keeptimes
While correction for physical decay is changed with option -d, sample
times will not be changed.
-nogap
Possible gap between time zero and first sample is filled.
--version or --build
Print software build information and exit
--silent
Program works silently, printing only error and warning messages
--verbose
Program prints more information about what it is doing.
