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 ...
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]
samtools view -h -b sample_sorted.bam "chr1:10-13" > tiny_sorted.bam Extract the same reads as above, but instead of displaying them, writes them to a new bam file, tiny_sorted.bam . The -b option makes the output compressed and the -h option causes the SAM headers to be output also.
Stampy is prepared to alignment of reads containing sequence variation like insertions and deletions. It is able to deal with reads up to 4500 bases and presents the output in SAM format. Subread [44] is a read aligner. It uses the seed-and-vote mapping paradigm to determine the mapping location of the read by using its largest mappable region.
Pileup format is a text-based format for summarizing the base calls of aligned reads to a reference sequence. This format facilitates visual display of SNP /indel calling and alignment. It was first used by Tony Cox and Zemin Ning at the Wellcome Trust Sanger Institute , and became widely known through its implementation within the SAMtools ...
The original CIGAR format from the exonerate alignment program did not distinguish between mismatches or matches with the M character. The SAMv1 spec document defines newer CIGAR codes. In most cases it is preferred to use the '=' and 'X' characters to denote matches or mismatches rather than the older 'M' character, which is ambiguous.
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 ...
The Variant Call Format or VCF is a standard text file format used in bioinformatics for storing gene sequence or DNA sequence variations. The format was developed in 2010 for the 1000 Genomes Project and has since been used by other large-scale genotyping and DNA sequencing projects.
