TAC file analysis made easy. fit_exp is a non-linear fitting of the sum of 1-3 exponential functions to plasma and tissue time-activity curves (TACs).
The function is: f(x) = p1*exp(p2*x) + p3*exp(p4*x) + p5*exp(p6*x).
TAC file must be in DFT format. Function parameters are written in fit or result format, depending on filename extension (.fit or .res).

Usage: fit_exp [Options] <TAC file> [Fit or Result file]

General options:
-h or --help
Print this message and exit
--version or --build
Print software build information and exit
Program works silently, printing only error and warning messages
Program prints more information about what it is doing

Other options:
-starttime=<Time (min)>
Set the sample time from where fitting is started (0 by default).
-endtime=<Time (min)>
Set the sample time where fitting is stopped (last sample by default).
Fitted TACs are written in DFT format
Fitted and measured TACs are plotted in specified SVG file
Names for fit file and fitted TAC file are set automatically
Weight by sampling interval
