E-DataAid works much like Excel, allowing the addition of columns (i.e., variables) and
modification of cell values. For example, to edit the value in a cell, place the cursor in the
appropriate cell, delete the current value, and simply type the new value. To select a column,
click the column header, and to move that column, click and drag the header to the new location.
Specific tool buttons, commands, and filtering abilities are included in E-DataAid to organize,
rearrange, or reduce the amount of data displayed.
2.11.2.2 Tracking modifications
E-DataAid includes additional features specifically designed to track modifications made to an E-
Prime data file (i.e., EDAT, EMRG). For example, all edits made to a data file (e.g., modification
of cell values, added variables, etc.) are displayed in red, indicating a modification to the file. In
addition, an annotation of each modification is written to an Annotations record saved with the
data file. The example Annotations record below (from a merged data file) indicates the single
subject data files from which the data originated, and notes that the subject number was modified
for one of the subjects (specifically, Subject 1 was changed to Subject 10).
The Annotations record serves as a history of merges and modifications to allow the user to track
not only the source files contributing to the master data file, but also any changes that were made
to the data.
