fit2dat 2.6.1 © 1996-2013 by Turku PET Centre
Program for calculating the PET time-activity curves (TACs) using
parameters of a mathematical function, which have been fitted to
the data previously.
Usage: fit2dat [Options] <Fitfile> <TAC file>
Fitfile must be in the DFT fit format; it contains the parameters
of the functions fitted to one or more PET TACs. Fitfile specifications:

Options:
-i Integrals of functions from zero to sample time are calculated;
not available for all functions
-h or --help

--version or --build

--silent
Program works silently, printing only error and warning messages
--verbose
Program prints more information about what it is doing
The sample times, where function values are to be calculated, can
be specified with one of the following options:
-A[=<stop>]
autointerpolate the data from 0 to stop time, or to fit range end time
(default), with decreasing sample frequency
-C=<start,stop,step>
specify the first and last sample time, and the sample frequence
-F=<file>
specify a DFT file, which contains the time framing information
-N=<nr>
specify the number of sample points between fit start and end times
-X=<x1,x2,x3,...>
specify the sample times individually
-R=<low,up,nr>
Specified nr of random x values between low and up are generated
-RST=<low,up,nr>
Specified nr of random x values between low and up are generated
with distribution biased towards low absolute values.
