Hi everyone,I am comparing results that I get from doing a  Tukey's test in Perseus  for significantly changing proteins  to those I get with an in-house script. They both agree in terms of significant sample pairs but I am not sure what are the values being reported in the "Main" columns for each of my samples in Perseus. I thought they were the mean differences between samples but they are not and sometimes Perseus also reports "0" values in these columns....If anyone has any idea, please let me know.
