The template used to abstract the data is located in file FINAL.TPL. Module 2 may be used to examine the template format and the dilution schedules (refer to Module 2 and Appendix B). Users may run the data abstraction module (Module 3) to produce the .STD, .UNK, .QC, and .LBL files. These are also included on the distribution diskette: MA112190.STD, MA112190.UNK, MA112190.QC, and MA112190.LBL.
Modules 4 may then be used to estimate the four parameters of the logistic-log fit. A sample file of standard curve fitting information is MA112190.FIT contains these results. A portion of that file is reproduced here:

Logistic-log and spline fit plots may be viewed using Module 5.
Module 6 may then be entered to calculate patient serum sample or unknown antibody concentrations. In this sample data set a calibration factor of 1500 was chosen. A complete listing of these results using the unweighted least squares fit is included in file MA112190.RPT. A sample of the report file is reproduced here:
