Binary Alignment Map (BAM) is the comprehensive raw data of genome sequencing; [1] it consists of the lossless, compressed binary representation of the Sequence Alignment Map-files. [ 2 ] [ 3 ] BAM is the compressed binary representation of SAM (Sequence Alignment Map), a compact and index-able representation of nucleotide sequence alignments ...
The SAM format consists of a header and an alignment section. [1] The binary equivalent of a SAM file is a Binary Alignment Map (BAM) file, which stores the same data in a compressed binary representation. [4] SAM files can be analysed and edited with the software SAMtools. [1] The header section must be prior to the alignment section if it is ...
samtools view -bS sample.sam > sample.bam. Convert a sam file into a bam file. The -b option compresses or leaves compressed input data. samtools view sample_sorted.bam "chr1:10-13" Extract all the reads aligned to the range specified, which are those that are aligned to the reference element named chr1 and cover its 10th, 11th, 12th or 13th ...
In the bitmap of any format, a 1 bit indicated the block was available (free), while a 0 bit indicated the block was not available (used), and the bitmap data was stored low-byte first. So the first byte held a map for blocks 0 to 7, the second byte held a map for blocks 8 to 15, and so on.
PacBio's (PACB) latest acquisition is expected to deliver the most advanced blend of sequencing solutions to transform the genomics landscape.
Alternatively, BAM file formats are preferred as they use much less desk or storage space. [ 14 ] Note : This is different from sequence alignment which compares two or more whole sequences (or sequence regions) to quantify similarity or differences or to identify an unknown sequence (as discussed below).

Compressed Reference-oriented Alignment Map (CRAM) is a compressed columnar file format for storing biological sequences aligned to a reference sequence, initially devised by Markus Hsi-Yang Fritz et al. [1] CRAM was designed to be an efficient reference-based alternative to the Sequence Alignment Map (SAM) and Binary Alignment Map (BAM) file ...
