TLK Model Input File #3
Sample Input Files

Tip: Comments are indicated in blue.  For additional details, click on the keywords highlighted in green. Reasonable default values are specified for all model inputs.

/*
TLK Model Sample Input File: Radiosensitivity parameters correspond to an alpha/beta ratio of 3.61 Gy. DSB repair is biphasic (fast repair half-time = 0.25 h, slow repair half-time = 7 hour).  The entire cell population is actively dividing (exponential growth kinetics), i.e.,
GF=1.  In addition to the radiation damage, endogenous processes are presumed to create 4.33E-03 DSB/cell-hour.

   Define multiple split-dose exposure scenarios (see also the s3.inp).  In this sample
   input file, a baseline exposure scenario is defined that delivers a total
   dose of 10 Gy as two 5 Gy fractions.  The fractions are delivered using an
   instantaneous dose rate of 100 Gy/hour.  The baseline scenario is then rescaled to
   deliver 20 Gy in two 10 Gy fractions.  The second fraction is delivered starting at
   the times indicated using the RX2 data array.  NOTE: Compare to the sdrx1.inp file.
