from filospot import DataNavigator, filter_spots_by_reference
from filospot.alignment import apply_pixel_translation

# Create a data navigator
navigator = DataNavigator()
navigator.load_paths(tif_dir, ref_dir, csv_dir)

# Apply image alignment
aligned_image = apply_pixel_translation(image, 0, 5, -2)
