What is Bioinformatics?

dragen 2Modern genomic analysis creates large volumes of data which is impossible for humans to analyse manually. At AWMGS the bioinformatics team uses a range of open source and in house software to process raw genomic data into more human readable formats. Once the data has been processed by our software clinical scientists can then interpret the results and generate the patient reports. The type of software used to process and analyse the data depends on the sample type. For example different software is required for samples from patients with inherited disease and those from cancer patients.

Bioinformatics at AWMGL

Within AWMGS the bioinformatics team develops and maintains the high quality computer software which underpins the laboratories diagnostic and research roles. The bioinformatics team has a range of skills in software development, data analysis, database design, web development, data science, machine learning and statistics. The team applies these skills to develop new tests, automate laboratory processes and ensure high quality patient results. The role of the team is expanding and the team is increasingly involved in other areas such as IT Infrastructure, training and quality control.
Some examples of recent successes includes: 
- Development of a pipeline for WINGS (Wales Infants’ & Children’s Genome Service); a whole genome sequencing service providing diagnosis to critically ill children.
- Expansion of our cancer services through validation of the TSO500 panel, enabling variants to be detected for a range of different cancer types.
- Validation of the Fetal Whole exome sequencing service, to aid the diagnosis of genetic conditions in fetal samples.
- Transferring and revalidating all our services on a new High Performance Computing cluster.
- Creation of new variant databases for analysing results to improve efficiencies in the service and enable patients to get results quicker.
- Development of a new samplesheet generator for easy adaptation in a rapidly expanding service.
The bioinformatics team develops software to process data from the laboratory’s Miseq, Hiseq, Nextseq and Novaseq instruments. Our bioinformatics software runs on a dedicated High Performance Computer (HPC) system to ensure that the data is processed rapidly. The team now supports the recently purchased DRAGEN platform which allows large amounts of genomic data to be processed much more rapidly than on a traditional computing system.

The Team

The bioinformatics team at AWMGS plays an increasingly vital role in delivering the services which the laboratory provides.
Acting at the intersection of biology and computer science, the team which comprises of bioinformaticians and trainees on the NHS Scientist Training Programme (STP) provide a range of specialised skills and services across the domains of data analysis, software development and genomic data processing.
