How to look up file retention settings in Illumina LIMS Project Manager

The Illumina LIMS (Laboratory Information Management System) facilitates high-throughput microarray processing and sample tracking through advanced automation and precise robotic control.

After BeadChips have been scanned and the scan data has been registered in LIMS, the system stores both the input files (DMAP files) and the output files generated during scanning (contained within the scan output folders). These files are not retained indefinitely. Instead, LIMS applies retention policies that determine how long each file type is stored within the system.

File retention settings can be viewed using the LIMS Project Manager application.

The following instructions describe how to view the file retention settings configured in Illumina LIMS. The retention period for files associated with a BeadChip begins once the BeadChip has progressed to the Image BeadChip Completed queue in LIMS.

1. Open the LIMS Project Manager.

2. Go to Tools > Administrator.
