Manually define ROIs

In this notebook, we (i) open the ROI interface for one video in the project, (ii) draw some ROIs on that video, (iii) duplicate those ROIs on the rest of the videos in the project, and lastely (iv) iterate over the videos in the project correcting The duplicated ROS.

# ONCE THE ROIs ARE DRAWN ON THIS VIDEO, REMEMBER TO CLICK "SAVE ROI DATA", AND THEN CLOSE ALL OPEN THE INTERFACE WINDOWS.

SIMBA COMPLETE: ROI definitions saved for video: 501_MA142_Gi_CNO_0514  complete

#NEXT, WE MULTIPLY ALL THE ROIs ON THE FIRST VIDEO ON THE LIST ON ALL OTHE VIDEOS IN THE SIMBA PROJECT (THIS PROJECT CONTAINS A TOTAL OF 100 VIDEOS)
multiply_ROIs(config_path=PROJECT_CONFIG_PATH, filename=video_file_paths[0])

SIMBA COMPLETE: ROIs for 501_MA142_Gi_CNO_0514 applied to a further 99 videos (Duplicated rectangles count: 1, circles: 0, polygons: 0).        complete

Next, click on "draw" to modify ROI location(s) or click on "reset" to remove ROI drawing(s)

#FINALLY, WE START TO ITERATE OVER ALL OTHER VIDEOS IN THE PROJECT (OMITTING THE FIRST VIDEO), AND CORRECT THE ROIs.
# I DON'T HAVE A GOOD WAY OF AUTMATICALLY OPENING THE NEXT VIDEO ONCE A VIDEO IS CLOSED AT THE MOMENT,
# SO WILL HAVE TO MANUALLY CHANGE `video_file_paths[1]` TO `video_file_paths[2]` etc.
