What are BAI files and how to open them
Are you having problems opening a BAI file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your BAI files.
What is a BAI file?
A .BAI file is a Binary Alignment/Map (BAM) Index file.
BAM files are a type of file format used for storing and exchanging genetic alignment information. BAM files are created by aligning DNA sequence reads to a reference genome, and they contain information about the location and alignment of each read on the genome.
BAM Index (.bai) files help speed up access and facilitate work with BAM files by providing an index. BAM Index files store information about the construction and contents of the matching BAM file. The BAM file can be rapidly and precisely searched for particular pieces of data without the need to read through its entirety, thanks to them.
BAM files are often employed in bioinformatic and genomics research, allowing rapid access and analysis of vast amounts of DNA sequence data. BAM files can also be used in other programs like genome browsers and variant callers.
