Data and code for:Hybridization-enabled magnetic capture and abundance-guided file identification in DNA data storage

This record provides processed sequencing inputs and Python code supporting the study “Hybridization-enabled magnetic capture and abundance-guided file identification in DNA data storage”. The dataset contains 64 counted FASTA files: 18 character-like bitmap samples and 46 image samples, including the corresponding mixed-input reference pools. These files contain preprocessed sequences annotated with their read multiplicities. The Python code includes sequence-component design utilities, JointEdit decoding, Strict read counting, regional enrichment and selectivity calculations, abundance-guided file identification, and bitmap/image reconstruction. Fixed reference dictionaries, sample correspondence tables, file-integrity manifests, dependency requirements and usage instructions are included. Each library’s input reference should be analyzed first, followed by experimental samples using the matching baseline.
