From IITA. We are analysing the data from the classical and Tricot consumer testing and the breeder urges to have an output from the analysis which shows the performance of all the varieties in the trial without relating to the check (relative performance of each variety as related to all the others). They want this logworth overview and muliticomparison for the complete set. We did this also in our consumer testing publication. Currently in the extra outputs that are generated this basic overview is not created (only in relation to checks). I would also be good to have such a basic file with all the data so people can make their own graphs. If not in the ClimMob report, I think this basic file with an accompanying heatmap and multiple comparison figure should be in the extra outputs. I think this is rather easy as it is the most basic analysis of the data.
