The parameter settings portion of the paradigm parameter file (PPF) is all the text before the 'return' statement. These parameters are in the form of standard CIGAL commands and will be executed as a command file.

The first line in the parameter list should be:

  showplay 0

in order to properly initialize ShowPlay. If the parameters and stimulus table are contained in the same file. The last line in the parameter specifications should be:

  return

followed by a blank line before the first line of the table.

Any valid CIGAL command can appear after the “showplay 0” line. Typically this section will set Showplay data variables, such as:

  sbackcolor = "black"
  stextcolor = 'white'
  t_r = 2000

For a list of Showplay data variables, see Control Variables.
