I am receiving an allocation error while using different expression calls (MAS5 and LiWong). This is happening during varying runs of a simulation. The actual errors are shown below. I'm not sure if this is a memory problem (I should have plenty of memory) or a BioConductor problem. Any suggestions? Thanks! #During MAS background correction: mas PM/MM correction : mas expression values: mas background correcting...Error: cannot allocate vector of size 32000 Kb #During LiWong normalization: invariantset PM/MM correction : pmonly expression values: liwong normalizing...Error: cannot allocate vector of size 32000 Kb

Yep, that's a memory problem. If you are running under Windows, you can make sure that you have enough memory allocated to R by using the command line flag --max-mem-size=1G (substituting the correct amount of RAM). If you have already allocated all your memory, then you have to get some more RAM. Regards, Jim James W. MacDonald Affymetrix and cDNA Microarray Core University of Michigan Cancer Center 1500 E.
