UniODA and CTA software require an ASCII (unformatted text) file as input data. Arguably the most difficult task an operator faces in conducting analyses is converting the original data file from (a) whatever software package was used to enter the data, into (b) an ASCII file for analysis. This article first highlights critical issues concerning missing data, variable labels, and variable types that users must address in order to convert their data into an ASCII file for analysis using ODA software. Specific steps needed to convert a data set from its original file-type into a space-delimited ASCII file are then discussed. The process of converting data into ASCII files for use as input data is illustrated for three leading statistical software packages: SPSS, SAS, and STATISTICA.
