GBS/RAD-seq Sequencing Data Analysis

Online Inquiry

CD Genomics uses bioinformatics to provide GBS/RAD-seq sequencing data analysis service. We perform high-throughput genome-wide single nucleotide polymorphism (SNP) discovery and genotyping of multiple DNA samples simultaneously based on sequencing data by GBS/RAD-seq. Our unique skills in data analysis will exceed our clients' expectations on personalized data analysis and provide the most comprehensive data analysis results.

What Is GBS/RAD-seq Sequencing Data Analysis?

Next-generation sequencing (NGS) technologies have revolutionized the way we study and understand the genetic makeup of organisms. Among these technologies, sequencing genotyping (GBS) and restriction-site associated DNA sequencing (RAD-seq) utilize restriction enzymes to target specific regions of the genome, thereby reducing the complexity of libraries that can be sequenced using NGS platforms. These methods enable the discovery and genotyping of SNP across the genome, providing valuable insights into genetic diversity, population genetics and evolutionary studies. GBS/RAD-seq sequencing data analysis involves the processing, analysis and interpretation of large-scale sequencing data generated by these techniques.

CD Genomics Data Analysis Pipeline:

At CD Genomics, we have developed a comprehensive data analysis process specifically tailored for GBS and RAD-seq sequencing data. Our expert team combines cutting-edge bioinformatics tools and custom algorithms to ensure accurate and efficient analysis of raw sequencing data. From data pre-processing and quality control to variant detection and genotype inference, our process covers all the essential steps in GBS/RAD-seq data analysis.

Reference-Based and De Novo Analysis

Our analysis process supports both reference-based and ab initio approaches to meet different research needs. In the presence of a reference genome, we can map sequencing reads to the reference genome and perform SNP calling and genotyping. For species without a reference genome, our ab initio analysis approach is able to identify several pairs of nearly identical reads representing alternative alleles at the locus.

Customized Analysis Strategies for Polyploid Organisms

Due to the complexity of genomes, polyploid organisms present unique challenges in GBS/RAD-seq data analysis. CD Genomics has developed novel and rigorous statistical methods for predicting the number of sequence reads needed to ensure accurate polyploid genotyping. Our expertise in handling polyploid data allows us to provide tailored analysis strategies and overcome the complexities associated with polyploidy.

Bioinformatics Support and Variant Analysis

Our team of bioinformatics experts at CD Genomics provides comprehensive support for GBS/RAD-seq data analysis. We provide services ranging from sequence pre-processing, alignment and variation analysis to interpretation of genetic markers. By leveraging advanced bioinformatics tools and algorithms, we can efficiently analyze large-scale sequencing data, discover meaningful genetic variation, and provide valuable insights into genetic diversity, population structure, and evolutionary patterns.
