What is GC Content?
GC content refers to the percentage of guanine (G) and cytosine (C) bases in a nucleotide sequence.
Description
- This tool calculates the GC content of the input nucleotide sequence.
- By checking "Calculate by window" and specifying the window size, the GC content is calculated for each window segment.
- When calculated by window, a line graph is displayed with the x-axis representing the start position of each window and the y-axis representing the GC content.
- By clicking "Download CSV file", you can download the GC content values for each window in CSV format.
- Both uppercase and lowercase letters can be used for the nucleotide sequence.
RNA-Seq Data Analysis Software
This is an RNA-Seq Data Analysis Software recommended for those who:
✔︎ Seeking to avoid outsourcing or collaboration for RNA-Seq data analysis.
✔︎ Lacking time to learn RNA-Seq data analysis.
✔︎ Frustrated by the complexity of existing tools.

Users can perform gene expression quantification, identification of differentially expressed genes, gene ontology(GO) analysis, pathway analysis, as well as drawing volcano plots, MA plots, and heatmaps.
