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.
