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
