Figure 2: Outline of the chemical reaction that underlies the bisulfite-catalyzed conversion of cytosine to uracil. Bisulfite[1] sequencing (also known as bisulphite sequencing) is the use of bisulfite treatment of DNA before routine sequencing to determine the pattern of methylation. DNA methylation was the first discovered epigenetic mark ...

The Variant Call Format or VCF is a standard text file format used in bioinformatics for storing gene sequence variations. The format was developed in 2010 for the 1000 Genomes Project and has since been used by other large-scale genotyping and DNA sequencing projects. [1][2] VCF is a common output format for variant calling programs due to its ...
