Dear Nextstrain community, I am J.K. Laerdahl from the National Hospital in Oslo. I want to find the short segments of the SARS-CoV-2 genome that are currently the most conserved and that clearly have no homoplasies. This resource, https://macman123.shinyapps.io/ugi-scov2-alignment-screen , was excellent, but is not updated since June last year. Is it possible to use Nextstrain? Or are any other resources better suited for this purpose using currently available data? Very likely I would like to use GISAID data (which I have access to).
