OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
The utility of the Oxford nanopore MinION sequencer is becoming clear. However, to fully exploit its potential requires a shift in thought in both experimental design and analysis. The conventional model of sequence, map and analysis leading to final result has been replaced by instant access to sequence data before the completion of a sequencing run. In the extreme case of the ONT MinION it is possible to analyse squiggle data before a read has even completed. We have developed a platform of tools, minoTour, to analyse MinION data in real time and extend it to exploit both ‘Run Until’ and, in future, ‘Read Until’. Run until allows the sequencer to switch off after achieving a specific goal, such as depth of coverage. Read until allows individual reads to be rejected from the pore and free that pore to sequence an alternative preferred read. We have developed method for run and read until in a number of different scenarios including selective small genome sequencing on barcode normalization. Limitations and challenges to implementing read until will be discussed along with the challenge of Fast Mode whereby speed of processing will be of vital importance. Finally we demonstrate how methodologies for analysing squiggles may help to reduce the reliance on base calling in the field.
