LPL 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.

/*
LPL Model Calibration Example: Use this sample file to begin analyzing delayed-plating cell survival data (no repopulation effects; GF=0.0).  If the dataset includes multiple dose rates (low and high dose rates), set the initial DSB yield (DSB parameter) to a value in the range from about 25 to 60 DSB/Gy-cell and adjust the FL, RHT (or LAM), and ETA parameters.  For small datasets, set the DSB parameter to a value in the range from 25 to 60 DSB/Gy-cell, and set RHT to a value in the range from 0.25 to 6 hour.  Then adjust the FL and ETA parameters.  For small datasets, it is very worthwhile to perform a few sensitivity studies to ensure that an optimal fit has been identified.  For example, performs fits with different values for DSB and RHT.
