Participants had the option of submitting predictions from multiple methods, and were asked to fill out separate template files for each different method. Each participant or organization could submit predictions from multiple methods, but could only have one ranked submission. Allowing multiple submissions gave participants the opportunity to submit prediction sets to compare multiple methods or to investigate the effect of varying parameters of a single method. All of the submissions were assigned a short descriptive method name based on the name they provided for their protocol in their submission file. This descriptive method name was used in the analysis and throughout this paper and is presented in Tables , and 5.
