Figure 2. Library types can be distinguished by their base compositions.

A) Number of samples per library type included in the analysis. B) UMAP representation of library compositions (reference map). C) Tile based probability map for each library type. Colour represents the percentage of a particular library type per tile. D) Heatmap illustrating the specificity of each library type for tiles of the reference map. All samples were assigned to a reference map tile and colour represents the average percentage of each library type for these tiles. E) Example of Librarian output: Librarian places each test sample in the two-dimensional space of the reference map. This heatmap shows the percent of each library type found in tile associated with the test library.
