Bioinformatics is a data-intensive field where accurate representation and exchange of biological data are critical. To facilitate seamless data analysis and sharing, bioinformatics relies on a plethora of file formats tailored to specific data types. From genomic sequences to protein structures, these formats are the backbone of computational biology. This blog post explores some commonly used bioinformatics formats with examples and their applications. 1. Sequence Data Formats FASTA Format The FASTA format is one of the most widely used formats for storing nucleotide or protein sequences. It begins with a single-line description, starting with a > symbol, followed by the sequence data. Example: >Gene1 Homo sapiens ATGCGTAGCTAGTACGATCG Applications: Storing DNA, RNA, or protein sequences. Input for sequence alignment tools like BLAST and CLUSTALW. FASTQ Format The FASTQ format combines sequence data and quality scores, making it essential for next-generation seque...
