Abstract

Here we describe the development of a novel software tool entitled Loader Lite that generates plate records or sample sheets for the ABI PRISM ® 3700 DNA sequencer. The major advantage of this program is that it enables the ongoing operation of sequencing instruments without reference to external network(s). The autonomous operation of sequencing instruments is critical if sample throughput is to be maintained during periods of network outage. Loader Lite employs a deliberate strategy of inputting anonymous tray barcodes at run time. After sequencing, the barcodes are reconciled with relevant project details by reference to a database. This software takes advantage of barcode scanning technology by creating plate records directly on the local computer, serving an individual sequencer, immediately before importing and linking. This real-time synthesis of the plate records at the point of loading all but eliminates loading errors. Loader Lite is user-friendly, fully configurable, and permits the running of partial or full 384-well sample trays, using any standard combinations of run modules, dye sets, mobility files, analysis modules, etc. The 96- well format is not supported; however, this capability will appear in subsequent versions that are currently under development. This application is designed as an added value, adjunct program to the regular ABI PRISM 3700 Data Collection software. We have successfully used Loader Lite over the past six months to load approximately 7 million sequencing reactions and believe its utility and functionality will prove to be attractive to the wider sequencing community.
