E-Prime data files may be merged to create E-Prime merged data files. When data from more than one session of data is combined into a single file, it is referred to as a merged data file. The process of merging involves selecting one or more E-Prime data files and performing a merge operation to combine the data from those files into a target file. Both single session data files and merged data files may be merged into other files (i.e., may be selected as source files). Single session data files may not be named as target files because they may contain only one session of data (i.e., data may not merged into them).
Selecting Source Files
A single file may be selected as a source file by simply clicking on the file name in the File List view to highlight it. Multiple files may be selected as source files concurrently by several methods described below.
The Select Unmerged tool button or the Select Unmerged command under the Edit menu will highlight all E-Prime data files in the File List view which have not been merged into another file.
The Select All command under the Edit menu will select all E-Prime data files (i.e., merged and unmerged, single session and merged data files).
Selecting Target Files
In order for a merge operation to take place, a target file must be designated as the destination for the source data. A target file may be set prior to a merge operation by clicking on an eligible file to select it, and choosing Set as Target under the File menu.
Eligible target files include existing E-Prime merged data files, or merged data files (.emrg3) created during a merge operation using the Set Target dialog. If the target file is set prior to the merge operation, the Set Target File dialog appears as a confirmation of the chosen target file.
NOTE: If the target file is in a different folder than the active folder, the merge operation will require the user to navigate to the target even though it may have previously been set as the target. This is viewed as a necessary inconvenience to prevent accidental merging to the wrong target file.
