The below script will allow you to generate thematic maps from the valuable Heliophysics Event Knowledgebase (HEK). I have written it to take a SUVI thematic map as input and output only Spatial Possibilistic Clustering Algorithm (SPoCA) coronal hole and bright region patches in HEK but would be willing to help assist others to modify the script as needed.

Expert labeled map

SPoCA map from HEK

The script can be found below and bundled with smachy, my solar image segmentation toolkit.

"""
Given a thematic map from SUVI this script queries HEK and creates a similar SPoCA thematic map with only
coronal holes and active regions.
