"""
DiseaseAssociatedSequenceOverlap report makes a heatmap showing the overlap of disease-associated sequences produced by :ref:`SequenceAbundance` encoders
between multiple datasets of different sizes (different number of repertoires per dataset).
This plot can be used only with MultiDatasetBenchmarkTool
The overlap is computed by the following equation:
.. math::
overlap(X,Y) = \\frac{|X \\cap Y|}{min(|X|, |Y|)} x 100
