We have just released a new version of the Nextclade web application clades.nextstrain.org for #SARSCOV2. We now use Nextalign (C++ via wasm) under the hood, which allows for many new exacting features!
A quick tour!
1/7
Analysis now takes a few seconds to start, but overall it has become much faster and analyzing hundreds of sequences should be no problem. You can download the reference alignments, including translations of SARS-CoV-2 genes, for further analyses.
2/7
You can now examine the diversity of the nucleotide alignment and alignments of different proteins. Select a gene from the drop-down or click on a gene in the genome annotation panel below.
Check out the new seqs from Angola (71), Nigeria (11) and South Africa (276) on nextstrain.org/ncov/africa. Botswana (1) currently not visible due to random subsampling.
New sequences from Botswana (2), Libya (1) and South Africa (4, currently not visible due to random subsampling) can be found on nextstrain.org/ncov/africa.
