N8 CIR UK Biobank Seminar Series

In June 2021 N8 CIR organised and hosted a series of seminars highlighting how researchers accessed and utilised UK Biobank data in their research.

Analysing the 100,000+ accelerometer datasets in the UK Biobank using the University of Manchester computational shared facilities

The UK Biobank contains over 100,000 records from participants who wore a wrist wearable device for a period of a week, allowing investigations into their activity patterns, sleep patterns, and more. The raw accelerometery data is more than 20 TB in size, with a large amount of meta-data also available.

This presentation will overview our computational approaches taken to analyse the entire dataset using the University of Manchester computational shared facilities, with optimizations to the storage and processing approach to accelerate the analysis. We will detail these optimizations, and our open source code for processing the data on high performance clusters and on Windows PCs.

We will also highlight some of the caveats and limitations of the dataset users should be aware of when designing their studies using it.

Extending the Reach of UK Biobank Data into the Mitochondrial Genome

Emma Drummond has developed a novel interpolation route which links microarray data to open-source libraries of full mtDNA sequence. Mitochondria are the cell organelle relied upon to provide ATP for all eukaryotic cells, which they must do efficiently and responsively.

The UKBiobank has collected a volume of data which enables an exploration of the human mitochondrial genome (mtDNA) for variants influencing mitochondrial performance. However, the density of the genetic data requires imputation, interpolating from known data points. Current methods fail to fully exploit what is known about the mtDNA and its inheritance pattern, which Drummond has improved upon.
