Introduced in , the "Deep" method (triggered by the --deep command) is a novel approach to co-compression . How It Works
: This effectively "hides" the FASTQ data within the BAM file's footprint, potentially halving the storage costs for genomic repositories. 15p.zip
: A co-compressed file containing both BAM and FASTQ data is typically only slightly larger than the BAM file alone . Introduced in , the "Deep" method (triggered by
: Despite the aggressive reduction, the process is bit-for-bit lossless. Using the Genozip platform , users can reconstruct the original FASTQ and BAM files exactly as they were. Performance and Impact 15p.zip
: It uses the BAM file's alignment data to "predict" the contents of the FASTQ files. Only the differences (residual information) between the two are stored.
