Fq_delta - Efficient storage of processed versions of fastq files
This technical note describes fq_delta, a python module and shell script that enables the storage of processed versions of fastq files generated by DNA and RNA sequencing technologies. By using Myer's diff algorithm to perform per-character comparisons between the original and processed fastq files, we generate delta files that describe the changes in the processed fastq file relative to the original file. While the delta files are only a fraction of the original size (0.1 – 3%), they allow lossless reconstruction of the processed fastq files. Depending on the number of processing steps, implementation of this module will lead to a significant reduction in storage required for processing sequence data.
