 -  **internals**: This key represents a modifier with respect to the ``'distance``' key. This can be helpful to annotate peaks to features with a wide size range, such as genes, which would otherwise be removed due to the distance thresholds. So even if the desired feature anchor is located too far away, a feature can still be included if it is overlapped.
+
    'center': If the center of a peak intersects with a feature region or vice versa, the ``'distance``' key filtering is disabled.  This parameter ensures that the majority of the peak intersects with the feature.
+   
    'any': If a peak intersects with a feature region or vice versa, the ``'distance``' key filtering is disabled. An overlap of >= 1 nt is sufficient.
+   
    Allowed values are one of ``'F', 'False', 'N', 'No'``, 'center', or 'any'.
    
    Default: ``'any'``
