fit_wliv - tpcclib 0.8.0 © 2023 by Turku PET Centre

Non-linear fitting of the liver radiowater model to TTACs using arterial
BTAC as the input function. Small delay of arterial input function is
fitted by default, as well as larger delay and dispersion representing
the portal vein input from GI system.
Usage: fit_wliv [Options] btacfile ttacfile [parfile]
     Delay time (sec) between BTAC and liver is constrained to given value.
     Delay time (sec) in GI system is constrained to given value.
     Dispersion in GI system is constrained to given rate constant (1/min);
     dispersion time constant tau=1/kGI.
     Blood volume is constrained to given value (mL/mL of liver).
 -w1 | -wf
     All weights are set to 1.0 (no weighting), or based on TTAC frame
     lengths; by default, weights in TTAC file are used, if available.
     Fitted and measured TACs are plotted in specified SVG file.
     Fitted TTACs at BTAC sample times are saved in specified TAC file.
 -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.
Sample times must be in seconds, unless units are specified in the file.
