Pangolin Web Application Documenation
Pangolin COVID-19 Lineage Assigner
Phylogenetic Assignment of Named Global Outbreak LINeages
This Web Application assigns lineages to COVID-19 sequences based on the methodology described in this article.
The application uses the software Pangolin developed by Áine O'Toole, JT McCrone, Verity Hill and Andrew Rambaut. The source code can be found here
The source code for the web application can be found here
Any issues with the application should be raised on the issue page
How to use
Assign a lineage to one or more COVID-19 sequences as follow
1) Upload one or more COVID-19 sequences by
a) dragging and dropping a (multi)fasta file of sequences onto the 'Drop Zone'
b) Clicking “Select a fasta file to upload” and selecting a (multi)fasta file of sequences.
2) Start Analysis
The uploaded sequences will be in the 'Ready for Analysis' state until you click on the 'Start analysis' button
The sequences will be uploaded and analysis will be started on the web server
3) Review results
On completion the lineage assignment a measure of the likelihood of the assignment will be displayed in the column marked 'Assignment probability'.
This is the assignment probability from the trained regression model, the probability of that sequence being the assigned lineage vs any other lineage.
Extra information about the lineage to which the sample has been assigned can be obtained by clicking on the tick button next to the sample
Next to each lineage assignment are 2 icons.
Clicking on the globe icon will open an interactive Microreact visualisation that shows the lineage selected in the context of global SARS-CoV-2 samples.
Clicking on the UK icon will open an interactive Microreact visualisation that shows the lineage selected in the context of the global SARS-CoV-2 sample collection but filtered for samples of UK origin
5) Upload another sequence file (Optional)
You can optionally analyse another file of COVID-19 sequences by clicking on the 'Upload another file' button, selecting a file and clicking on 'Start analysis again'
6) Download results
The results can be downloaded in CSV format
If you need to reset the analysis at any time, just click on the 'Reset entries' button
