2 Merge

The second step in data preparation is to merge the individual .edat files into a single .emrg file.

The individual subject data files are located on the Z Drive:

Z:/Backup Data/[STUDY NAME]/Subject Files/[DATE]/[Task Name]

You need to save the merged data files on the Z Drive to:

Z:/Backup Data/[STUDY NAME]/Merged

  1. Open E-Merge 3.0 by clicking on the icon in the task bar.

  2. In the left window pane, navigate to the directory:

    Z: Backup Data / [StudyName] / Subject Files / [DATE]

  3. Click on the [Task Name] folder. This should populate the right window pane with .edat files

  4. Select all the files (Ctrl + A)

  5. Click on Merge in the toolbar above

  6. Select Standard Merge

  7. A finder window will pop up asking you Save the merged data file.

    Save it to:

    Z: Backup Data / [StudyName] / Merged

    If there is already a merged file for this task, select that file to overwrite it.

    If there is no merged file for this task yet, it will ask you if you want to create this file. Select “Yes.”

    Save the new merged data file with the same name as the [Task Name] folder.

  8. Conflict: A message box might pop up saying “a conflict occured.” If this happens, then select the “Merge the sessions into the target file” option and select OK.

  9. Repeat steps 3 - 8 for each task folder

    • The directory tree in the left window pane may have disappeared. To make it reappear, adjust the horizontal size of the window panes by moving your mouse cursor to the divider between the left and right window panes.

You should now see E-Merged files for each task located in Z:/Backup Data/[STUDY NAME]/ Merged.
