smftools.plotting.umi_plotting

Plotting utilities for UMI bipartite graph analysis.

Functions

plot_umi_bipartite_summary(count_matrix, ...)

Plot a fidelity scatter of U1-U2 pairing quality.

smftools.plotting.umi_plotting.plot_umi_bipartite_summary(count_matrix, sample_name, reference_name, save_path=None)

Plot a fidelity scatter of U1-U2 pairing quality.

Each point is a unique (U1_cluster, U2_cluster) pair. Position shows the fraction of that cluster's reads accounted for by this pairing (U1 fidelity on x, U2 fidelity on y). Point size and colour encode read count. Dominant 1:1 pairs cluster at (1, 1); chimeric noise sits at lower values.

Return type:

None

Parameters

count_matrixpd.DataFrame

Rows = U1 cluster consensus sequences, columns = U2 cluster consensus sequences, values = read counts.

sample_namestr

Sample identifier (used in title).

reference_namestr

Reference identifier (used in title).

save_pathPath or None

When set, saves figure as PNG at 300 dpi. Otherwise displays.
