Introduction of Circos

Circos. Circos is a software package for visualization of data and information. Because of its unique display form, it is an ideal tool for exploring the relationship between objects and positioning. The Circos diagram can be used to conveniently display various types of information, and is particularly suitable for displaying different levels of data information in the form of Circos circles. Due to these advantages of the Circos diagram, it is often used in different fields to present data analysis results. In the field of life sciences, Circos diagrams were originally mainly used for the visualization of genomic sequence-related data, and have now been used in many fields, such as the enrichment of metabolic pathways, species diversity and genome coverage. In short, most relational data can be visualized with Circos.

Circos is easy to plot, format and layer your data. A large variety of plot and feature parameters are customizable, helping you make the image that best communicates your data. You supply your data to Circos as plain-text files, tell Circos what you want plotted using the configuration file, and then create the image.

Application Field

Cancer genomics.

Comparative genomics.

Molecular biology.

Whole genome copy number map analysis.

Systems biology analysis.

Tabular data visualization.

The circos software package can be used in a variety of biological information data analysis scenarios, and the generated pictures are very beautiful and intuitive. As long as you have a certain basis of bioinformatics analysis, you can quickly learn how to use Circos. But if you don't have enough time and energy to learn how to use Circos, but you want to show your research results through Corcos diagrams, then you can contact us at any time. CD Genomics has a professional biological information analysis team. You only need to provide the original data, and we will provide you with biological data analysis and make result charts. Looking forward to working with you!
