Images are in JPEG format. The .spj file is a project file for use with Microsoft Image Composite Editor v2.0 (https://www.microsoft.com/en-us/research/product/computational-photography-applications/image-composite-editor/). Python scripts are written for Python v3.6+ and require non-standard libraries matplotlib, Numpy, opencv-python, picamera, PIL, pytest, scipy, and scikit-image, all of which are available from the Python Package Index (https://pypi.org/). The analysis script `run_analysis.sh` requires a global installation of the Python library micat (https://gitlab.com/bath_open_instrumentation_group/micat). It may be executed directly by a UNIX-like shell, but the command invocation it contains may be used on other platforms.
