OALogin processing shows the same well/vial injected from twice and the next injection missed - WKB228416

Article number: 228416

SYMPTOMS

  • OpenLynx Browser shows incorrect information, which when reprocessed resolves the issue
  • OALogin/OpenLynx processing shows the same well/vial in a plate injected from twice and the next injection missing
  • OpenLynx shows multiple injections from same vial when only one injection occurred
  • Experimental records show the processed files as identical, not different injections
  • The History.inf file is present only in the first injection raw data folder, not the second

ENVIRONMENT

  • MassLynx
  • OALogin
  • OpenLynx
  • Diversity Browser

CAUSE

Processing error/corruption by OpenLynx due to the system submitting a new sample for analysis before it has finished processing the first sample.
Note: OALogin uses OpenLynx processing.  

FIX or WORKAROUND

Disable parallel processing as described in this article: How to disable parallel processing on a PC - WKB17597

ADDITIONAL INFORMATION

OALogin is submitting samples to the queue for injection/analysis and then processing via OpenLynx. With parallel processing enabled, OALogin submits a second sample for injection after the first acquisition has completed but before the first sample is processed. The system becomes confused, processing sample 1 twice—once after it has acquired sample 1 and then again at the end of sample 2. This is shown by the history.inf file in sample 1 having a different time than the end of its run time.

Processing 1 twice creates two entries in the OALogin report file for that well. Then, the processing command has been consumed for sample 2, so it is not processed.

Reprocessing sorts out the confusion.

Disabling parallel processing forces OALogin/OpenLynx to complete the processing of sample 1 before it acquires sample 2, preventing the timing corruption.
