 The percentage deviation in the processing of 26 images between 1) the PTRAP automatic results (PTRAP raw data) and the corrected data after expert evaluation and 2) between the corrected PTRAP 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).
