Background of the Study :
Next-generation sequencing (NGS) technologies have revolutionized biomedical research by enabling the rapid generation of large-scale genomic data. However, the analysis of this data remains a significant challenge due to the complexity and volume of information produced. This study aims to evaluate various NGS data analysis techniques and their effectiveness in disease research, using datasets from Usmanu Danfodiyo University, Sokoto State. The research will compare methodologies for data preprocessing, alignment, variant calling, and functional annotation to determine which techniques yield the most reliable and clinically relevant results. By integrating bioinformatics pipelines with state-of-the-art machine learning algorithms, the study seeks to enhance the accuracy and speed of NGS data analysis (Ibrahim, 2023). The evaluation will also consider factors such as computational efficiency, scalability, and ease of use. Recent advancements in NGS analysis have led to the development of several innovative tools that can handle large datasets, yet their performance can vary significantly depending on the specific disease context and data quality (Adeyemi, 2024). This study will systematically assess these tools by applying them to genomic data related to various diseases prevalent in the local population. Furthermore, the research will explore the impact of different data preprocessing strategies on downstream analysis outcomes. The study emphasizes the need for standardized protocols and quality control measures to ensure the reproducibility of results. By identifying the most effective NGS data analysis techniques, the research aims to provide a framework that can be adopted by researchers and clinicians in resource-limited settings. Overall, the evaluation is expected to contribute to improved disease research methodologies, leading to better diagnostic and therapeutic strategies. The outcomes will inform future developments in NGS data analysis and support the broader adoption of these technologies in biomedical research (Chinedu, 2025).
Statement of the Problem :
Although next-generation sequencing has transformed biomedical research, significant challenges persist in the analysis and interpretation of the vast amounts of data generated. Many current analysis techniques struggle with issues such as data noise, alignment errors, and inconsistent variant calling, which can lead to unreliable results. In resource-constrained environments, these challenges are further compounded by limited computational resources and expertise, resulting in suboptimal use of NGS data for disease research (Ola, 2023). Existing tools and pipelines often lack standardization, making it difficult to compare results across different studies and laboratories. This variability can undermine the reproducibility of findings, which is critical for translating research into clinical applications. Moreover, the rapid evolution of sequencing technologies means that analysis methods must be continually updated, posing an ongoing challenge for researchers. This study seeks to address these issues by systematically evaluating and benchmarking NGS data analysis techniques using local datasets from Usmanu Danfodiyo University. By identifying the strengths and limitations of various methods, the research aims to establish best practices and standardized protocols for NGS data analysis in disease research. Addressing these problems is essential for maximizing the utility of NGS data, improving diagnostic accuracy, and ultimately advancing personalized medicine initiatives. The study will provide recommendations for optimizing existing pipelines and highlight areas for future improvement, ensuring that researchers can extract meaningful biological insights from complex genomic datasets (Ibrahim, 2025).

By identifying optimal methods and best practices, the research will improve diagnostic accuracy and enhance personalized medicine approaches. The findings will be especially beneficial for researchers in resource-limited settings, enabling more efficient and reliable analysis of complex genomic data (Adeyemi, 2024).
