fit_disp - tpcclib 0.7.8 © 2022 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
