fit_wrlv - tpcclib 0.7.3 © 2019 by Turku PET Centre

Non-linear fitting of exponential input function with paired, repeated
eigenvalues, incorporating injection schedule, to RV and LV cavity BTACs
from a radiowater PET study, where LV BTAC is modelled with simple
delay and dispersion of the RV BTAC.
 
Usage: fit_wrlv [Options] tacfile [parfile]
 
Options:
 -Ti=<infusion time>
     Duration of intravenous infusion in seconds; 0, if short bolus.
 -w1
     All weights are set to 1.0 (no weighting); by default, weights in
     output data file are used, if available.
 -wf
     Weight by output TAC 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.
 
TAC file must contain two TACs, for RV and LV, in this order.
Sample times must be in seconds, unless units are specified in the file.
