Example 19.1 An example of preprocessing a set of survival data for the purpose of estimating the parameters. Survival data for different radiation doses for E. coli are reported from a series of experiments as shown in the following table. | Experiment No: | 1 | 2 | 3 | 4 | 5 | 6 | 7 | | Dose (Gy) | 0 | 45 | 90 | 135 | 180 | 225 | 270 | | Surviving fraction (S) | 1.000 | 0.706 | 0.564 | 0.395 | 0.261 | 0.193 | 0.116 |
Simulating the given set of data can be processed as a set of 7 experiments using XIO so that an exposure scenario can be created with the provided data to run VC. The batch file created for this purpose invokes the input file cho.inp, which indicates the file in which the exposure scenario and the FAR data are to be found, ecoli.inp. Executing the batch file mak.bat with all these three files in the same folder location will yield the necessary files for the VC execution. Open the file cho.out to see that the input data such as the dose, dose rate and the survival data are properly processed.
Tip: Check the output file (e.g., cho.out) to verify that the VC interpreted the exposure scenario specified in the input file is the desired one.
