Evaluation of different crowding levels and SNR levels. a Precision and recall curves of particle picking at different crowding levels using a scaling factor of 7 (low = crowding level 1 with 2000 particles, medium = crowding level 2 with 5000 particles, high = crowding level 3 with 8000 particles), and tomograms with SNR = 50. b F-scores for particle picking across all threshold levels t and scaling factor 7, grouped by different crowding levels. c Precision and recall curves for particle picking at different SNR levels, using low crowding level 1 (with 2000 particles) and scaling factor 7. d F-scores for particle picking across all threshold levels t and scaling factor 7, grouped by different SNR levels
