E-DATAAID: Add Variables [22810]

Adding Variables

Variables may be added using the Add Variable command in the Edit menu. The Add Variable command displays a dialog allowing the user to define a new variable’s name, its level (session, block, trial), and its data type (string, integer, float). The new variable will be added as a new column at the end of the spreadsheet.
 

Adding a variable to a data file marks the file as containing altered data, displays the new variable in color, stores a global annotation describing the addition of the new variable, and updates the modified date for the file. Variables may be added to a data file with the restrictions that the name of the variable must be fewer than 80 characters and must begin with a letter, the name may only include valid characters (letter, numbers, periods and underscores), and the name cannot be “Subject”, “Session”, “ExperimentName”, or the name of any other existing variable or level.
