GTZ

GTZ is a software tool that is designed to provide efficient lossless compression of FASTQ data while simultaneously transmitting it to cloud storage. With the explosion of DNA sequencing technology, there has been a surge in the creation of large-scale genomic data, which necessitates the development of a tool that can efficiently compress and transmit data to cloud storage at a faster and cheaper rate. This is where GTZ comes in, as it is a reference-free lossless FASTQ compressor that treats different lines of FASTQ separately, utilizes adaptive context modeling to estimate their characteristic probabilities, and compresses data blocks with arithmetic coding.

Moreover, GTZ is optimized for FASTQ files and can be employed to compress multiple files or directories at once, making it a highly efficient and useful tool for NGS data storage and transmission in the cloud environment. It can also save compressed data locally or transmit data directly to cloud storage, providing users with a choice of storage options.

The performance of GTZ has been evaluated on diverse FASTQ benchmarks, and the results have shown that it outperforms many other compression tools in terms of compression ratio, speed, and stability. With its ability to efficiently compress and transmit FASTQ files, GTZ emerges as a valuable tool for researchers and scientists who work with NGS data and require an efficient and reliable data storage and transmission tool.
