Unmapped bam
WebA BAM file is the binary, compressed version of the SAM file. It is significantly smaller in size and is usually the file format requested for by downstream tools that require alignment data as input. The paper by Heng Li et al provides a lot more detail on the specification. … WebFeb 25, 2024 · uBAM - Unmapped BAM Format Follow. uBAM is a variant form of the BAM file format in which the read data does not contain mapping information. This is basically an "off-label" use of the BAM format (which was specifically designed to contain mapping …
