The Application of DDCA to Metagenomic Analysis
With the advent of the next-generation sequencer (NGS), sequencing costs have dramatically declined, but data analysis still costs as much as before or more. One of the reasons is that for NGS data analysis, it is necessary to key in commands on Linux which is a less common operating system. Therefore, we have developed the digital DNA chip analysis (DDCA) system which processes NGS data to produce results similar to microarray that are familiar to wet researchers. With this system, it is not necessary to have a high-performance computer in the laboratory, and analysis can be performed by using simple mouse operations on a web browser. After uploading sequence data to our server, users can click on some options to perform an analysis called digital hybridization on DDCA. In this paper, after describing the DDCA system, we introduce the procedure to analyze metagenome data using actual sequence data.
