Wrong assignment for 20A NCOV sequences

[HadrienRegue]

Dear nextstrain team,

First, thank you for your work!

We recently updatated our nextclade sars-cov-2 classic dataset (from 2024-06-13T23:42:47Z to 2024-07-17T12:57:03Z).
however, our last sequencing positive control results are wrong using this dataset where 20A->20C. Our 20H control remain correctly assigned.

When using the mature protein sars-cov-2 dataset, our 20A positive control is correctly assigned.

Can you have a look on this problem?
I can provide you our postive control sequences if needed.

Best regards,

Hadrien

Thanks for the report Hadrien! I'll have a look - could you possibly send me the fasta of the sequence that changed in its assignment? that would simplify the checking. You can also send it by email if you prefer that over sharing here (as txt)

Bellow are the 3 sequences generated from our last sequencing results.
