Summary

match_template.py facilitates template matching using various scoring metrics.

match_template.py --help

preprocess.py enables template generation, masks can be created interactively using preprocessor_gui.py or the API.

Note

match_template.py expects high densities to have positive (white contrast), low densities to have negative values (black contrast). Therefore, input tomograms typically need to be inverted by multiplication with negative one. Version 0.1.4 introduced the --invert_target_contrast flag, which automatically performs the inversion for you.

As of version 0.2.1 you can alternatively provide an appropriately scaled template. This template does need to be centered and match_template.py needs to be invoked with the --no_centering flag.
