## Unreleased | ||
|
||
- fix: Increase Nextclade alignment parameter "excessBandwidth" from 9 to 12 to correctly align complex series of indels that has arisen in Spike NTD with the occurrence of S:31- in some JN.1. The bandwidth is chosen to be as small as possible (to ensure fast runtime) but as large as necessary for correct alignment. As a result, occasional adjustments like here are required. Nothing else is changed in this SARS-CoV-2 dataset update. | ||

# SARS-CoV-2 dataset with mutations relative to BA.2.86 | ||
|
||
| Key | Value | | ||
| ----------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------- | | ||
| authors | [Cornelius Roemer](https://neherlab.org), [Richard Neher](https://neherlab.org), [Nextstrain](https://nextstrain.org) | | ||
| reference | `Wuhan-Hu-1/2019` with BA.2.86 SNPs added | | ||
| workflow | https://github.com/neherlab/nextclade_data_workflows/tree/v3-sc2/sars-cov-2 | | ||
| path | `nextstrain/sars-cov-2/BA.2.86` | | ||
| clade definitions | [Nextstrain clades](https://nextstrain.org/blog/2022-04-29-SARS-CoV-2-clade-naming-2022) and [Pango lineages](https://www.nature.com/articles/s41564-020-0770-5) | | ||
|
||
## Scope of this dataset | ||
|
||
This dataset shows mutations relative to the prototypical BA.2.86 sequence and is particularly useful for the analysis of SARS-CoV-2 sequences that are descended from BA.2.86. | ||
|
||
For the analysis of non-BA.2.86 sequences, other Nextclade datasets for SARS-CoV-2 may be more appropriate. In addition, the `wuhan-hu-1/proteins` dataset shows amino acid mutations in coordinates of mature proteins (nsp1-16) instead of ORF1a and ORF1b coordinates. | ||
|
||
## Reference sequence and reference tree | ||
|
||
The reference sequence in this dataset is `Wuhan-Hu-1/2019` but with BA.2.86 SNPs added. SNPs (but not indels) are thus shown with respect to BA.2.86 while the mutation positions remain within the familiar `Wuhan-Hu-1` coordinate system. | ||
|
||
The reference tree contains one sequence for each Pango lineage descended from BA.2 (including recombinants such as XBB) and is rooted on BA.2. | ||
|
||
## Features | ||
|
||
This dataset supports: | ||
|
||
- Assignment of Nextstrain clades | ||
- Assignment of Pango lineages | ||
- Sequence QC | ||
- Phylogenetic placement | ||
- Calculation of ACE2 binding scores relative to BA.2.86 as described in [Starr et al. 2022](https://doi.org/10.1371/journal.ppat.1010951) | ||
|
||
## Nextstrain clades | ||
|
||
Since its emergence in late 2019, SARS-CoV-2 has evolved into many co-circulating variants. To facilitate discussion of these variants, we have grouped them into clades which are defined by specific signature mutations. | ||
|
||
Nextstrain clade names consist of two numbers representing a year and then a single letter representing the clade within that year. For example, 21A is the first clade we named in 2021. | ||
|
||
We define each clade by a combination of signature mutations. You can find the exact clade definition on Github in this [file](https://github.com/nextstrain/ncov/blob/master/defaults/clades.tsv). | ||
|
||
Below is an illustration of the phylogenetic relationships of Nextstrain clades ([source](https://github.com/nextstrain/ncov-clades-schema/)): | ||
