Abstract

Biological electron microscopy is currently going through a revolution in terms of usability and the attained results in terms of the resolution (~quality) of the resulting reconstruction. The current state-of-the-art programs RELION 2.1 and cryoSPARC are very GPU intensive and we have a large need for access to GPU equipped computing nodes to process data and perform reconstructions of data collected primarily at SciLife but also other resources available through EU-wide access programs. With electron microscopy programs that we will run on the cluster we will analyse biological supermolecules involved in mitochondrial RNA processing, nuclear pore transport relevant for cancer progression (KI) and membrane protein complexes involved in cellulose synthesis (KTH). The analysis goes in cycles with very heavy analysis for up to a month followed by a calmer period.
