draw_rectangle1 (WindowHandle, Row1, Column1, Row2, Column2)
gen_rectangle1 (Rectangle, Row1, Column1, Row2, Column2)
reduce_domain (Image, Rectangle, ImageReduced)
crop_domain (ImageReduced, ImagePart)


create_shape_model (ImagePart, 'auto', -0.39, 0.79, 'auto', 'auto', 'use_polarity', 'auto', 'auto', ModelID)

write_shape_model (ModelID, 'C:/Users/CF/Desktop/shapeModel1.shm')
