If the target does not exist prior to the merge operation, it will be created by E-Merge during the operation. Target files may or may not be located in the same directory as the source files, and may or may not exist prior to the merge operation. Single session files may not be named as target files because data may not be merged into them. The target file is the file into which sessions of data are to be merged during a particular merge operation. Merged data files may be merged into other files (i.e., act as a source file) or receive data from other files (i.e., act as a target file). Merged data files have the EMRG extension. Merged data files are E-Prime data files which contain data from more than one session, and which are not designated as the target file. Single Session files have the EDAT file extension.
Single session files are E-Prime data files generated by the E-Run application, which contain data from a single session. The Status column remains blank for non-E-Prime files. The Status column contains one of three values for E-Prime files: Single Session, Merged data, or Target. Refer to E-STUDIO: Experiment Object for more information. The Data File tab on the Experiment object’s Property pages allows the user to set parameters related to the writing of data files, and the names to be used for log levels within the data file.
