It is designed for short and long reads generated by sequencing platforms and is standard within the Genome Analysis Toolkit (GATK).

While optional, keeping the header (which includes details like @SQ for reference sequences and @RG for read groups) is highly recommended. SAM- fl.zip

It contains 11 mandatory fields for essential alignment information (such as query name, flag, reference sequence name, position, mapping quality, etc.) and a variable number of optional fields. It is designed for short and long reads

Based on the context, typically refers to the Sequence Alignment/Map format used in bioinformatics for storing nucleotide sequence alignments. reference sequence name
