In early builds of AskiaAnalyse version 5.3.3, the feature export a sub-population, if the option exported to inverted database was selected, was creating incorrect level ID files. This meant that when interviews were merged from the inverted file, developed questions were not read in askiaanalyse 5.3.4. If you cannot re-export the data with AskiaAnalyse version 5.3.4 or later, you can use this feature to fix the problem with the inverted database.

To use this feature:

1. Open a QES file with the open inverted file command.
2. In the tools menu, select fix inverted files.
