Why do I see "Project integrity" errors in the Empower message center? - WKB91863

ENVIRONMENT

• Empower

ANSWER

A "project integrity failed" message is not caused by a user deleting data using Empower software. Project integrity testing was enhanced in the Empower 3 SR3 release.

The project integrity test fails for any of the following reasons:

• Data is incomplete due to a detector or an instrument failure that occurred during acquisition. One of these messages appear in the Channel Status field in the Review chromatogram window: No data acquired or Data incomplete. The data file is present, but contains incomplete data.
• The project was backed up or you performed an on-demand integrity test while acquiring data.
• The LAC/E module lost communication with the server and was in buffering mode while data was being acquired during a project integrity test.
• The project integrity test detects fewer data files (channels) than expected. A privileged user, such as a system administrator, deleted raw data files, or data files were manipulated or modified improperly during a project backup.
• Issues with the computer's hard drive caused the loss of data integrity of the data file.
• Virus activity modified the data file.
• Data files were removed or quarantined by antivirus software.
• The *.EXP and/or *.INF file checksums differ. "Bad Checksum" message appears on the chromatogram plot in the Review window.
