1Productivity
If next generation sequencing (NGS) is used to generate high-throughput sequencing data, then the throughput capability is improved, but existing analysis techniques are insufficient to take advantage of the throughput capabilities
Solution Approach 1:
The analysis platform divides the sequencing data processing into distinct modular tools including short read alignment, protein alignment, de novo assembly, and statistical analysis components. Each tool handles specific aspects of the data, allowing the system to manage high-throughput NGS data through specialized, manageable modules rather than a monolithic complex system.
Solution Approach 2:
The analysis platform is designed as a universal system that can handle multiple types of sequencing analyses simultaneously - DNA read alignment, protein sequence alignment, de novo genome assembly, and statistical analysis of single nucleotide variations. This multi-functional approach allows the system to fully utilize NGS throughput capabilities across diverse analytical needs.
2Measurement precision
If in vitro screening is performed for virus detection, then detection of specific genetic sequences is achieved, but the process is time consuming and costly with single virus targeting
Solution Approach 1:
The platform provides a universal detection system that can screen for multiple viruses and genetic sequences simultaneously through high-throughput sequencing analysis, eliminating the need for separate targeted screenings for each virus. The short read alignment and protein alignment tools can detect various viral contaminants in a single comprehensive analysis.
Solution Approach 2:
The system uses computational copying and comparison of sequence reads against reference genome databases to identify viral sequences. Rather than physical replication or repeated physical screenings, the platform creates virtual copies of reference genomes and compares sequencing data against these digital references, dramatically reducing time and cost while maintaining detection precision.
3Measurement precision
If PCR testing is used for genetic sequence detection, then specific range detection is achieved, but the detection range is limited
Solution Approach 1:
The analysis platform provides universal detection capability that can identify a broad range of genetic sequences including viruses, bacteria, and other contaminants through high-throughput sequencing. The system maintains PCR-like specificity through precise alignment algorithms while expanding detection range to cover multiple pathogen types simultaneously, unlike PCR which is limited to predetermined targets.
Solution Approach 2:
The platform employs dynamic alignment parameters and adjustable matching criteria that can adapt to different types of genetic sequences and contamination levels. The alignment tolerance for mismatches, insertions, and deletions can be adjusted based on the specific analysis needs, providing both high specificity for known sequences and flexibility for discovering novel variants.
4Measurement precision
If microscopy is used for virus detection, then visual detection is achieved, but throughput is low and detection consistency is unreliable
Solution Approach 1:
The platform replaces manual microscopy-based visual detection with automated computational analysis of sequencing data. The short read alignment and protein alignment tools automatically compare sequence reads against reference databases using algorithmic methods, eliminating the need for manual visual inspection under microscopes. This substitution dramatically increases throughput while improving detection consistency through standardized computational criteria.
Solution Approach 2:
The system performs self-service detection through automated alignment algorithms that independently identify viral sequences without human intervention. The platform automatically processes sequencing data, compares it against reference genomes, identifies matches, and generates results without requiring manual microscopy or expert visual analysis, thereby increasing both throughput and reliability.

AI summary
A sequencing data analysis platform can process datasets that include a large number of sequence read. The reads are aligned to one or more reference genomes. Due to sequencing errors, sequencing noise, or genuine differences between a reference genome and the individual species being sequenced, this mapping process may tolerate a certain number of mismatches, insertions, or deletions. The sequencing data analysis platform provides a set of tools for analyzing and visualizing the sequence reads.
