fit2dat - tpcclib 0.8.0 © 2023 by Turku PET Centre

Calculates the PET time-activity curves (TACs) using parameters of
a mathematical function, which have been fitted to the data previously.
Usage: fit2dat [Options] fitfile tacfile
Fitfile must be in the DFT fit format; it contains the parameters
of the functions fitted to one or more PET TACs. Fitfile specifications:
 -i  Integrals of functions from zero to sample time are calculated;
     not available for all functions.
 -h, --help
     Display usage information on standard output and exit.
 -v, --version
     Display version and compile information on standard output and exit.
 -d[n], --debug[=n], --verbose[=n]
     Set the level (n) of debugging messages and listings.
 -q, --quiet
     Suppress displaying normal results on standard output.
 -s, --silent
     Suppress displaying anything except errors.
 The sample times, where function values are to be calculated, can
 be specified with one of the following options:
     autointerpolate the data from 0 to stop time, or to fit range end time
     (default), with decreasing sample frequency.
     specify the first and last sample time, and the sample frequence.
     specify a TAC file, which contains the time framing information.
     specify the number of sample points between fit start and end times.
     specify the sample times individually.
     Specified nr of random x values between low and up are generated.
     Specified nr of random x values between low and up are generated
     with distribution biased towards low absolute values.
