Quality control

Quality control (QC) is a set of procedures used to ensure the quality of data or products. In the context of next-generation sequencing (NGS), QC is used to identify and remove errors and biases in sequencing data. This is important to ensure that the data is accurate and reliable for downstream analysis.

There are a variety of methods that can be used for QC of NGS data. Some of the most common methods include:

• Read quality: This assesses the quality of individual reads, such as the number of errors and the average base quality.
• Sequence alignment: This aligns reads to a reference genome to identify errors and biases.
• Data filtering: This removes reads that are of low quality or that are likely to be erroneous.
• Statistical analysis: This uses statistical methods to identify patterns in the data that may indicate errors or biases.

The choice of method depends on the specific research question being asked and the available resources.

When working with NGS data, it is essential to take safety precautions to avoid contamination. This includes using gloves, a lab coat, and a face mask. It is also important to work in a designated area that is free of contamination.

When working with sequencing data, protecting the privacy of the individuals being analysed is crucial. This includes using secure storage and transmission methods. It is also essential to be aware of the ethical implications of using sequencing data.

QC is used in a wide variety of applications, including:

• Data analysis: QC ensures that the data is accurate and reliable for downstream analysis.
• Data interpretation: QC can be used to identify patterns in the data that may indicate errors or biases.
• Data quality assessment: QC can be used to assess the data quality and identify areas that need improvement.
• Data reproducibility: QC can be used to ensure that the data is reproducible.

QC is an essential part of any NGS project. By ensuring the quality of the data, QC can help to improve the accuracy and reliability of the results.
