Genomic File Formats
When working with genomics data for the first time, many engineers are surprised to find that genomics file types are quite simple in structure. In fact, a majority of universal file formats such as SAM/BAM, VCF, BED, GFF/GTF and many other custom formats are essentially tab-delimited text files with some form of compression and/or serialization. In this chapter, we cover the main file formats one might run into when working in the genomics domain, starting with common compression schemes.
