LFastqC

LFastqC compresses FASTQ files losslessly without requiring reference genomes to reduce storage and transmission needs for next-generation sequencing (NGS) data from platforms such as LS454, PacBio, and MinION.

Key Features:

• Lossless Compression: Ensures no data is lost during compression, preserving original sequencing information for downstream analyses.
• Non-Reference-Based: Operates independently of reference genomes or external references.
• Improved Compression Ratios: Demonstrates superior compression ratios compared with state-of-the-art compressors on NGS datasets including LS454, PacBio, and MinION.
• Enhanced Speed: Provides improved compression and decompression speed relative to its predecessor LFQC.
• Redundancy Exploitation: Exploits inherent redundancy within NGS FASTQ datasets to achieve compression gains.

Scientific Applications:

• Genomic data storage and transmission: Reduces storage space and transmission bandwidth required for large-scale NGS datasets.
• Research infrastructure and data management: Facilitates management of NGS data in environments such as data centers across diverse sequencing technologies.

Methodology:

Builds on LFQC by refining and optimizing a non-reference-based algorithm that exploits inherent redundancy in NGS FASTQ datasets to improve compression ratios and speed.
