Hello,   I am trying to figure out what the default separation method is when I run this PROC Glimmix code. Usually I specify it to run Tukey, but when I remove that specification from my code I wanted to know what method is the default that runs? Code Example Below: proc glimmix data=crapes; class trt rep color; model arl = color trt color*trt; random rep; lsmeans color trt color*trt/diff lines; run; quit;   Typically in the lsmeans line I have adjust=tukey, but as I stated I am curious as to what program runs the means separation when that statement is removed and it runs as typed above.   TIA!
