SARS-CoV-2 and SARS-CoV-2-no-recomb
Bug fix release (tag 2022-07-26T12:00:00Z)
Fix: Ancestral reconstruction of mutations was wrong due to recombinants attaching directly to the root and causing the root mutations to be different from Wuhan.
This caused:
- displayed mutations in Auspice to be wrong for all tips since around the time recombinants were first included in the tree (since
2022-03-24T12:00:00Z) - Some of the calculated reconstructed mutations on recombinants to be wrong, affecting nearest neighbor placement of some recombinants.
The fix will cause a few recombinants to become recombinants and improve QC values of some recombinants but should not have large effects overall.
The biggest perceived impact will be that mutations displayed by Auspice will now be correct.
