Oxford Nanopore Technologies VBZ HDF plugin for h5py
Project description
VBZ-H5Py-Plugin
This module provides a plugin to H5Py for the VBZ (de)compression library.
VBZ Compression
VBZ compression is a compression algorithm developed by Oxford Nanopore to reduce file size and improve read/write performance when handling raw data in POD5/Fast5 files. Previously, the default compression was GZIP and comparing to GZIP we see a compression improvement of >30% and a CPU performance improvement of >10X for compression and >5X for decompression. Further details of the implementation and benchmarks can be found here: Nanoporetech/vbz_compression
Usage
