**ShowPlay Reference Manual, Chapter 1 (Introduction): inputfiles**
===== Inputfiles -- =====
As input, ShowPlay requires a text file with a '.ppf' extension. The two types of information needed for a '.ppf' file to run in showplay are listed below. These two parts of the ppf file must appear in this order with a 'return' statement at the end of the paradigm parameters settings and a blank line between them.

  * [[jvs:cigal:showplay:manual:chapter1:stimulustypes|file types]]
  * [[jvs:cigal:showplay:manual:chapter1:stimuluscommands|commands]]

(Note: text files with a '.txt' extension will also run if the file contains the requisite information, but the '.ppf' extension is convention and is useful in distinguishing your stimulus files from other text files.)
