Preprint on the NYC sequences - pretty interesting. https://www.biorxiv.org/content/10.1101/2021.02.14.431043v2.full.pdf

If this is from NYC, it's possible they used Illumina's DRAGEN pipeline

Interesting - we have seen quite a lot of 'reversions' in some of the VOCs. Who would be using this consensus caller? Is there a way to find out?

I'm worried A LOT of people are using the Illumina pipeline - and there's no way to find out in most cases

Any lab that hasn't previously been involved in virus sequencing and isn't as comfortable with command line tools would likely use this caller. It's a big big problem.

Interestingly, none with both (kinda supporting this is a real effect - since they're independent events): https://outbreak.info/situation-reports?pango=B.1.526&muts=S%3AE484K&muts=S%3AS477N
