The 17 lines above show a sample input file, which must be named 
BTinput, for the program BACKTRAN.

When modifying the input file BTinput, ensure that the modified file 
has 17 lines containing the information below. If the line contains 
text, rather than numbers, enclose the text in quotation marks ("). If 
more than one number per line is required, enclose the list of numbers 
in brackets ({}), and separate the numbers with commas.

line 1: The name of the file where output will be written enclosed in 
quotation marks.

line 2: User selected wording that will be placed at the top of the
output file. Ensure that the total line length, including quotation
marks is less than 72 characters.

line 3: User selected wording that will be placed at the top of the
output file. Ensure that the total line length, including quotation
marks is less than 72 characters.

line 4: The initial time interval at which observations were made. For 
example, hour 1. Note: a control time of 0 should not be included. 
Control data are not used to calculate the regression line, but are used 
only to adjust for control mortality.

line 5: The last time interval at which observations were made. For 
example, hour 5.

line 6: The size of the intervals desired for the output data set. For 
example, if time goes from hours 1 to 5 you may want output in hourly 
intervals so set line 6 equal to 1. If time goes from 1 to 120 hours, 
you may want a ten-hour interval, so set line 6 to 10.

line 7: Set to "yes" if log10 of time was used in the analysis, 
otherwise, set to "no".  Enclose in quotation marks.

line 8: Indicate whether "probit", "logit", or "cll" transformation of y 
was used in the analysis.  Enclose in quotation marks.

line 9: Intercept from analysis.

line 10: Slope from analysis.

line 11: Indicate whether you would like residuals calculated and 
printed to the output file (yes or no in quotation marks).

line 12: Number of time intervals for which data will be entered.

line 13: The observed cumulative number of insects dead in the control 
at each time interval, enclosed in brackets.

line 14: The observed cumulative number of insects dead in the treatment 
at each time interval, enclosed in brackets.

line 15: The times at which observations were made, enclosed in brackets.

line 16: The initial number of insects in the control.

line 17: The initial number of insects in the treatment.
