Hello all, I am trying to run a repeated measures analysis on feeding behavior variables in a Randomized Complete Block Design. The measurements were repeated on animals weekly. I have ~1800 rows of data and want to run it all at once for proper analysis of the effect of treatment, week, and the interaction. Here is the code I originally ran: Data ELORA; infile "/home/mwilli200/ELORA.PhD.2022/Feeding Behaviour Data.csv" dlm="," firstobs=2; input ID$ group block tmt$ week dintake wintake timefe visit timevisit vsize rate meal timemeal msize; run; proc sort data=elora; by id; run; *************************************************; proc glimmix data=ELORA1 plots=studentpanel; class block tmt ID week; model dintake= tmt week tmt*week/ ddfm=kenwardroger; random block block*tmt/ subject=id; random week/ residual type=arh(1) subject=id; lsmeans tmt tmt*week week/ pdiff adjust=tukey lines; *output out=second predicted=pred residual=resid residual(noblup)=mresid student=studentresid student(noblup)=smresid; run; I received the following error message: ERROR: The SAS System stopped processing this step because of insufficient memory. I ran the exact same program with only including weeks 1-4 to cut the number of rows down to 480. Below is the error message: ERROR: The SAS System stopped processing this step because of insufficient memory. NOTE: PROCEDURE GLIMMIX used (Total process time): real time 2.83 seconds user cpu time 0.48 seconds system cpu time 2.35 seconds memory 4115670.81k OS Memory 4136412.00k Timestamp 03/27/2023 04:00:10 PM Step Count 51 Switch Count 7 Page Faults 0 Page Reclaims 958039 Page Swaps 0 Voluntary Context Switches 42 Involuntary Context Switches 5 Block Input Operations 0 Block Output Operations 544 I understand there are data limitations for this program (5 gb) but this is my only platform option currently and I have a Mac. Any help would be greatly appreciated. Melissa,
