The 17 lines above show a sample input file, which must be named 
BT2input, for the program BACKTRN2.

When modifying the input file BT2input, 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 lowest dose at which observations were made. Note: a control 
dose 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 highest dose at which observations were made.


line 6: The size of the intervals desired for the output data set.  For 
example, if dose goes from 0 to 1 mg you may want output in 0.1 mg 
intervals so set line 6 equal to 0.1.

line 7: Set to "yes" if log10 of dose 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 doses for which data will be entered.

line 13: The observed number of insects dead in the control.

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

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

line 16: The initial number of insects in the control. If the number of 
insects dead in the treatment at each dose has already been corrected 
for control mortality, set line 16 equal to any integer greater than 0.

line 17: The initial number of insects tested at each dose, enclosed in 
brackets.
