**i have 2 samples A & B proteome data analyzed using progenesis software. i have max fold change reported to be infinity. How will i convert these fold change to log2fc values for heat map generation?
From a mathematical point, log(Inf) = Inf.
biologically these are significant proteins which are unique to one particular sample
If you don't want/can't use Inf, you need to come up with a replacement value. For visualization purposes, I guess any value that's higher than the max of the rest of the data could do. What to do really depends on what you want to achieve.
