Viral Lineage

​

Introduction

​

This page contains the results of the analysis on the different viral lineages of SARS-CoV-2 which have been downloaded from GISAID. This analysis is organized in a series of interactive PowerBI dashboards which are described below. Details of the methods used are contained in the Methods page and possible avenues of expanding this work are given in the Future Directions page.

Dashboard ​

​

Cluster Visualization 

​

This dashboard allows one to visualize the individual data points across the entire dataset from GISAID, in terms of mutations of genes in both nucleotide or amino acid space (mode), the locations of the samples (map), how the cluster according to gene similarities (scatter plot) and details of the individual samples (table).

​

Clicking an individual country on the map allows one to see the subset of individual samples (table) below with their cluster identities and gene mutations and how they lie in the cluster space (scatter plot).

​

The scatter plot shows the first two principle components of the features (aligned gene similarities) which the data is clustered on. One can click on an individual point and show the details of individual samples (table). One can also click on an individual cluster in the legend of the scatter plot and see the countries (map) where it is found together with the details of the individual clusters (table).

Demographic Proportions 

​

This dashboard shows the percentage of samples belonging to a particular clusters by demographic factors such as gender and age group.
