var4dat 1.3.2 © 1999-2012 by Turku PET Centre
Program for adding Gaussian noise to time-activity data.
If optional isotope letter is specified, variance is increased by decay.
If datafile contains weights, then the specified amount of variance is
added to frames with weight=1, and higher or lower variance to those
frames with lower or higher weight.
Usage:
var4dat <CV%> <Data file> <Output file> [Isotope code]
Options:
-S[eed]=<seed for random number generator>
Computer clock is used by default
-sec
If datafile does not contain time unit, times are by default assumed to
be in minutes. Use this option to set time unit to sec.
-h or --help
