wvar4dat 1.2.1 © 2002-2008 by Turku PET Centre

Program for adding Gaussian noise to time-activity data. SD is assumed to be equal to (noise level)*sqrt(1/weight), and the weights must be included in the DFT datafile (e.g. dftweigh). Usage: wvar4dat <Datafile> <Noise level> <Output file> Options: -S[eed]=<seed for random number generator> Computer clock is used by default -h or --help Print this message and exit --version or --build Print software build information and exit --silent Program works silently, printing only error and warning messages --verbose Program prints lots of information about what it is doing. TAC file format is specified in http://www.turkupetcentre.net/analysis/doc/format_dft.html See also: dftweigh, var4tac, fvar4tac, wvar4dat, tacmean, rescoll Keywords: DFT, noise, simulation This program comes with ABSOLUTELY NO WARRANTY.
