hello all, I know problems regarding memory allocation has been asked a number of times and i followed those solutions too but still i am not able to resolve this issue.... > fns2=list.celfiles(path="C:/Program Files/R/R-2.10.1/koolfile",full.names=TRUE) > rawdata=ReadAffy(filenames=fns2) Error: cannot allocate vector of size 640.9 Mb > memory.size() [1] 1294.3 > memory.limit() [1] 2047 > memory.size(2047) [1] 2047.88 > memory.size(4095) [1] 4095 > rawdata=ReadAffy(filenames=fns2) Error: cannot allocate vector of size 640.9 Mb I want to read files of size 810Mb,62 celfiles.......I checked the memory.size and memory.limit functions....also i tried to increase the memory size by adding "C:\Program Files\R\R-2.10.1\bin\Rgui.exe" --max-mem-size=2GB" in the target.but still it dint help....following are the details of my pc Processor : Intel(R)Core(TM)2CPU 6320@1.86GHz Memory(RAM): 2038Mb System type:32-bit-operating system [[alternative HTML version deleted]]

Looks like you do not have enough physical memory for what you are trying to do. You may need to try using another package for affy analysis or using another machine with more RAM. Sean

It depends a bit what kind of analysis you are trying to do, but the aroma.affymetrix framework solves most memory issues (even if you only have 1GB of RAM): http://www.aroma-project.org/ /Henrik On Thu, Apr 8, 2010 at 10:51 AM, sneha patil <snp2312 at="" gmail.com=""> wrote: > hello all, > > ? ?I know problems regarding memory allocation has been asked a number of > times and i followed those solutions too but still i am not able to resolve > this issue.... > > >> fns2=list.celfiles(path="C:/Program > Files/R/R-2.10.1/koolfile",full.names=TRUE) >> rawdata=ReadAffy(filenames=fns2) > Error: cannot allocate vector of size 640.9 Mb >> memory.size() > [1] 1294.3 >> memory.limit() > [1] 2047 >> memory.size(2047) > [1] 2047.88 >> memory.size(4095) > [1] 4095 >> rawdata=ReadAffy(filenames=fns2) > Error: cannot allocate vector of size 640.9 Mb > > I want to read files of size 810Mb,62 celfiles.......I checked the > memory.size and memory.limit functions....also i tried to increase the > memory size by adding "C:\Program Files\R\R-2.10.1\bin\Rgui.exe" > --max-mem-size=2GB" in the target.but still it dint help....following are > the details of my pc > > Processor : Intel(R)Core(TM)2CPU 6320 at 1.86GHz > Memory(RAM): 2038Mb > System type:32-bit-operating system > > ? ? ? ?[[alternative HTML version deleted]] > > _______________________________________________ > Bioconductor mailing list > Bioconductor at stat.math.ethz.ch > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor >
