Values in Post-hoc Tukey's results

[Manuel Ivan Villalobos Solis]

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.

Thanks,

Ivan.
