fit_bpr 0.2.0 © 2010-2012 by Turku PET Centre
Non-linear fitting of a function to sampled blood-to-plasma ratio data.
Usage: fit_bpr [Options] <Data file> <FIT file>
Options:
-model=<igv|hillb|ihillb>
Select the metabolite model; default is IGV
-delay[=<time>]
Fit also delay time, or, set delay time (0 by default)
-bl=<baseline>
Constrain baseline level to specified value; fitted by default
-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
-fast or -safe
Speed up the fitting but increase the chance of failure, or
increase the reliability at the cost of computing time
-min=<ss|abs>
Sum-of-squares (SS) is minimized by default, but optionally
sum of absolute deviations can be selected
-svg=<Filename>
Fitted and measured TACs are plotted in specified SVG file
-h or --help
Print this message and exit
--version or --build
Print software build information and exit
--silent
Program works silently, printing only error and warning messages
--verbose
Program prints more information about what it is doing.
Datafile can be any DFT file (1) which can include weights.
Program writes the fit start and end times, nr of points, WSS/n,
and parameters of the fitted function to the FIT file (2).
Example:
fit_bpr -model=igv -svg=ia765bprat.svg ia765bp.rat ia765bprat.fit
