Lineage prediction from SARS-CoV-2 sequences

Armadillin

A Re-engineered Method Allowing DetermInation of viraL LINeages

Armadillin is an experimental alternative approach to training models on lineages designated by the PANGO team.

Armadillin uses dense neural networks for assignment, which means it doesn't have to assume that positions with an N are the reference sequence. Armadillin is still very fast.

Installation (for inference)

conda create --name armadillin python=3.9
conda activate armadillin
pip3 install armadillin

Usage

You must already have aligned your files to the reference (doing this automatically is on the backlist).

We'll use the COG-UK aligned file for a demo:

wget https://cog-uk.s3.climb.ac.uk/phylogenetics/latest/cog_alignment.fasta.gz

armadillin https://cog-uk.s3.climb.ac.uk/phylogenetics/latest/cog_alignment.fasta.gz

or

armadillin https://cog-uk.s3.climb.ac.uk/phylogenetics/latest/cog_alignment.fasta.gz > output.tsv

Training your own models

While training code is in the repo, it is not quite in working order today and needs a little work.
