fit_disp - tpcclib 0.8.0 © 2023 by Turku PET Centre
Non-linear fitting of dispersion and delay from system input and output
curves.
Usage: fit_disp [Options] inputfile outputfile [parfile]
Options:
-min=<OLS|LAD>
Sum-of-squares (OLS) is minimized by default, but optionally
sum of absolute deviations (LAD) can be selected.
-w1
All weights are set to 1.0 (no weighting); by default, weights in
data file are used, if available.
-wf
Weight by sampling interval.
-svg=<Filename>
Fitted and measured TACs are plotted in specified SVG 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.
Data files must contain 2 columns, sample times and concentrations,
possibly also weights as last column.
Example:
fit_disp -svg=delayfit.svg input.tac output.tac delayfit.par
