E-DATAAID: Adding and Renaming 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.

Renaming Variables
Variables may be renamed 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 cannot be “Subject”, “Session”, “ExperimentName”, or the name of any other existing variable or level.

Variables and level names may be edited using the Rename Variable command in the Edit menu. The Rename Variable command displays a dialog allowing the user to enter a new name for the variable or level.

When a new name is entered, the application will search the data file, and will display an error if the new name is already used by another variable or level in the file. The search is not case sensitive.

 
Editing a variable or level name marks the data file as containing altered data, displays the edited variable or level name in color, stores a global annotation describing the edit, and updates the modified date for the file.
