The version is 2.7.3, fit_exp, 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...
