Visualization of geographic location from selected viral genomes. Uncultivated viral genomes and genome fragments (UViGs) can be accessed differently. (1) Here, UViGs from the viral cluster ‘vc_2912’ were selected from the ‘Viral Clusters’ link in the IMG/VR Home Page and added to the ‘Scaffold Cart’. (2) 14 UViGs were retrieved and a feature table displayed (not shown in the figure). (3) To obtain a Google Map with the location of the selected UViGs, users need to get back to the Home Page and select ‘Scaffold Cart’ from the ‘Ecosystem’ drop down box above the map. Map pins (in red) represent location counts of viral contigs and may contain multiple samples. Map pins are grouped into clusters (bold number in a coloured square based on number of members within the cluster) according to the Google Map javascript API utility library. (4) As you zoom into any of the cluster locations, the number on the cluster decreases, and you begin to see the individual markers on the map from which specific UViGs can be selected. Zooming out of the map consolidates the markers into clusters again.
