  1. The table above summarizes the sequencing of Run116 on both the MiSeq and the GridION. The sequencing runtime for the MiSeq was 36 h, whilst that of the GridION was 21 h. The MiSeq had a Q30 score of 73.1% with 70% of the clusters passeing QC The flowcell used for the GridION had 1012 pores available for sequencing. Of the 93 samples sequenced by both platforms, 93 consensus genomes were produced by each. Consensus genomes from the MiSeq had an average coverage of 94.34% with 89.2% having a coverage of 80% and over. Consensus genomes from the GridION had an average coverage of 72.96% with 27.9% having a coverage of 80% and over
