Format Conversion

Definition

Format conversion is the process of transforming data from one file format to another, which is crucial for compatibility and usability in computational genomics. This ensures that data generated in one format can be effectively utilized in different software tools and platforms. In the context of genomic data, format conversion is essential for processing sequence alignments and variant calls, which are often stored in formats like SAM/BAM and VCF.
