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. [4]
Raw PacBio subreads use the same convention but typically assign a placeholder base quality (Q0) to all bases in the read. [7] Oxford Nanopore Duplex reads, called using the dorado basecaller are typically stored in SAM/BAM format. After changing to a 16-bit internal quality representation, the reported base quality limit is q50 (S). [8]
samtools sort -m 5000000 unsorted_in.bam sorted_out. Read the specified unsorted_in.bam as input, sort it in blocks up to 5 million k (5 Gb) [units verification needed] and write output to a series of bam files named sorted_out.0000.bam, sorted_out.0001.bam, etc., where all bam 0 reads come before any bam 1 read, etc. [verification needed] index
Word methods identify a series of short, nonoverlapping subsequences ("words") in the query sequence that are then matched to candidate database sequences. The relative positions of the word in the two sequences being compared are subtracted to obtain an offset; this will indicate a region of alignment if multiple distinct words produce the ...
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]
The format allows for sequence names and comments to precede the sequences. It originated from the FASTA software package and has since become a near-universal standard in bioinformatics. [4] The simplicity of FASTA format makes it easy to manipulate and parse sequences using text-processing tools and scripting languages.
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 ...
