NextSeq 550Dx Software
The instrument software includes integrated applications that perform sequencing runs or array
scanning.
u NextSeq Control Software (NCS)—The control software guides you through the steps to set up a
sequencing run or an array scan.
u Real-Time Analysis (RTA) software—For sequencing runs, RTA performs image analysis and base
calling during the run. The NextSeq 550Dx instrument uses RTA v2, which includes important
architecture and feature differences from earlier versions. For more information, see
Real-Time
Analysis
