| 27 | All existing items need to be assigned external ID values. A simple procedure is to export 4 data files with the internal ID of each item. One file for patients, one file for cases, one file for blood and one file for specimen and nospecimen items. Use a spreadsheet program to add a second column with auto-generated external ID values. Import the text files back into BASE using the built-in batch importer plug-ins. |
