You can view the Sample Report in a tree (or phylogram) format. The tree depicts the taxonomic hierarchy of all microbes identified in the sample you have selected. Below we discuss some features found within the tree view.
Tree View
By default, when you first open the Sample Report page you will see the Table View. Use the View Toggle ( ) to switch to the Taxonomic Tree View by clicking the phylogram icon. The resulting visualization shows the taxonomic relationships among identified microbes.
Tree Line Thickness: The weight of the lines connecting tree nodes is proportional to the metric currently selected from the Tree Metric Dropdown Menu. By default, the thickness of the lines is based on NT reads (NT r). In the example below highlighting the metric dropdown menu, a thicker line between nodes indicates a higher NT r for taxa.
Line colors: The blue lines highlight lineages for taxa that have the top three Aggregate Scores in the report (otherwise, the lines are grey). These top scoring taxa have more than 1 reads per million matching the NT and NR databases (NT rPM > 1 and NR rPM > 1) and are found in higher abundance in samples than in negative controls (NT Z score > 1 and NR Z score > 1). In the Table View, top scoring taxa are flagged with a lightbulb icon.
Filters: You can apply or remove filters just like you can filter the sample report table.
Exploring the Tree: You can explore the tree by selecting different nodes. Click on nodes to expand or collapse branches extending from a node. A plus sign indicates that there are species under a given node. Click the plus sign to expand the branches under the node and view species names.
