The percentage deviation in the processing of 26 images between 1) the P-TRAP automatic results (P-TRAP raw data) and the corrected data after expert evaluation and 2) between the corrected P-TRAP data and field operator results (FO). The factors assessed (Traits) were Rachis length (PA_length), Number of nodes (Nodes_nb), Number of secondary Axes (SA_nb), Average length of Secondary Axes (SA_length), Number of tertiary axes (TA_nb) and the Number of grains (Sp_nb). The results were calculated for the mean of differences, standard deviation (STD), and the deviation sign (Sign).
